The document discusses stakeholders engagement in policy development. It explains that stakeholder engagement is the process of involving individuals affected by or able to influence an organization's decisions. Key stakeholders in policy development include the public, policymakers, advocacy groups, employees, and consumers. There are several reasons for engaging stakeholders, such as improving decision making and ensuring policies address community needs. Stakeholder engagement occurs at different stages of the policy cycle, from agenda setting to evaluation. Stakeholders provide valuable feedback and help identify risks, thus impacting policy development. However, challenges include identifying representative stakeholders and determining how to incorporate diverse input. Overall, the document argues that stakeholder engagement is important for developing effective policies.

The Six Phases of the MapReduce and Hadoop in Data Analytics Life Cycle is listed in the following order: Discovery, Data Preparation, Model Planning, Model Building, Communicate Results, and Operationalize. True False 10 points QUESTION 2 1. In the MapReduce paradigm, it is stated that the reduction time to complete a given task by breaking it down into stages and then executing those stages in the parallel is activity also called: Data/Worker and Pattern/Chunks Slave/Retrieval and Data/Chunks Data Retrieval and Master/Pattern Master/Slave and Master/Worker 10 points QUESTION 3 1. Under YARN, the content and structure of a MapReduce job is unchanged, but how the scheduling and management of the job is quite different. The Job Tracker functionality is now shared by the Resource Manager and the Application Master
(App Master). The key steps include which of the following: The client submits a MapReduce job to the Resource Manager which schedules the job based on cluster activity. From the Name Node, the Application Master determines on which nodes the HDFS blocks are stored and builds an execution plan and resource requirements. The Application Master starts the Map tasks and monitors their status. All of the Above. 10 points QUESTION 4 1. Query Languages for Hadoop builds on core Hadoop (MapReduce and HDFS) to enhance the development and manipulation of Hadoop clusters and have the following three components: * Java Scripting * VBA Coding * Match Tables True False 10 points QUESTION 5 1. HBase represents a further layer of abstraction on Hadoop. HBase has been described as “a distributed column-oriented
database [data storage system]” built of top of HDFS. HBase uses additional Apache Foundation open source frameworks such as Zookeeper, which is used as a co-ordination system to maintain consistency, Hadoop for MapReduce and HDFS, and Oozie for workflow management. True False 10 points QUESTION 6 1. In regard to “In-Database” functions, Greenplum supports certain set operations as part of a SELECT statement. Which of the following is NOT a part of a SELECT statement?: The INTERSECT - Returns rows that appear in all answer sets. REMOVE ALL - Removes the previous executed set of data from the latest answer set. EXCEPT - Returns rows from the first answer set and excludes those from the second. UNION ALL - Returns a combination of rows from multiple SELECT statements with repeating rows. 10 points QUESTION 7 1. In regard to the Greenplum SQL OLAP Grouping Extensions, Greenplum supports the following grouping extensions: Rollup - This extension provides hierarchical grouping.
Cube - Complete cross-tabular grouping, or all possible grouping combinations, is provided with this extension. Grouping Sets - Generalized grouping is provided with the GROUPING SETS clause. All of the above. 10 points QUESTION 8 1. In regard to the techniques discussed around text analysis. It is common practice to store the parsed data from an unstructured source in a database for down-stream analysis. With the advent of Hadoop and its ecosystem products, unstructured data can also be stored in external tables and accessed by traditional relational databases. True False 10 points QUESTION 9 1. Window function is described as a function that performs a calculation across a set of table rows that are somehow related to the current row. But unlike regular aggregate functions, the use of a window function does not cause rows to become grouped into a single output row as the rows retain their separate identities. True False 10 points QUESTION 10 1.

The topic chosen for the research paper is “Stakeholders Engagement in Policy Development .” It is accompanied with the problem statement of examining the way the stakeholders’ engagement in the policy development is used to develop the policies together with the impacts of the stakeholders in the development of the policies. 1. Introduction The stakeholder’s engagement is referred to as the process whereby the organization involves the individuals that will be affected or can influence the decisions to be made. The stakeholders either support or opposes the decisions which will influence the organization both internally and externally. The stakeholders’ engagement has been seen to improve the decision making in a given organization. The main aim of this paper is to examine the way the stakeholders’ engagement in the policy development is used to develop the policies together with the impacts of the stakeholders in the development of the policies. While most of the organizations have the interest in engaging the stakeholders in the issues to deal with the policies, there is a great divergence when the stakeholders are engaged. This includes the purpose of the stake holders, when to engage them during the development of the policies, the methods to be used for the engagement, their impact, challenges, and the outcome of using the stakeholders. 2. Key Stakeholders to be Involved in the Development of the Policies Stake holders are the group of people or the organizations that are involved in the process of the policy development. In any of the organization, the stakeholders includes the public, the policy makers, researchers, the advocacy groups, employees, and the consumers among other people who are affected by the law (Lemke, 2015). Each of the stake holders comes up with his or her different opinion in the development of the policies. However, there are six major types of stakeholders. These are the customers, employees, investors, suppliers, communities,
and the government (Corperate Finance Institute, 2019). As the different stakeholders have the different interests, their contribution to the development of the policies is different. 3. Reasons for Engaging the Stakeholder In the stakeholders’ engagement, there is different reasons as to why they are involved. Among them is the production of the quality decision making. Secondly is for the avoidance of the duplication of the policies together with the identification of the commonality. Thirdly is to increase the effectiveness and the efficiency of the policy as it will be covering all round. Fourthly, it increases the practices of the risk management. Fifth, it enhances a great sensitivity of the policy to all the needs and the wants of the community. Sixth, there is a high degree of confidence of the policies together with the transparency as the practices will be aligned with the needs of the society. Lastly, it helps in increasing the accountability of the investments of the public resources hence trustworthy and quality policies (Lemke, 2015). All these reasons makes the policy to be effective and supporting both the external and the internal environment of the organization in one way or the other. As a result of these, there is a development of the effective and efficient policies. 4. Stages for the Policy Development Even though there are no guidelines and the rules for the development of the policies, the roles of the stakeholders play a major role in the process of the decision making. The general stages for the policy development are as follows. The agenda setting, analysis, formation of the policies, implementation, review and the evaluation of the policies (Siu, 2013). With the different phases for the policy making, the different stakeholders are being in the different phases for the cycle of the policy development. At this level, it is also where we will be able to know the exactly when the stakeholders will be engaged in the process of the policy development. This steps can be skipped, reversed or even recycled throughout the lifetime of the development of a single policy (Lemke, 2015).
5. Impacts of the Stakeholders in Policy Development Stakeholders are the very important bodies in the development of the policy. They have a lot of impacts in that they give the valuable feedback and the information which is important is important in the development of the policies. Besides, they help the cooperation to identify the risks in the development of the policies together with the external risks that might affect the policies and running of the organization. The stakeholders are very important as they are the ones which led to the success of the company. 6. Challenges Faced The engagement of the stakeholders in the policy development has several challenges. The first challenge is the identification of the right stakeholders who will well represent a large group. Secondly are the resources which are needed for facilitate the engagement of the stakeholders to all the processes for the policy making (O'Neill, 2011). Thirdly is to determine the ways in which the input of the stakeholders together with the different cultures that are involved among the different stakeholders. Lastly is the challenge of articulating all that could be done by the stakeholders. 7. Conclusion In conclusion, we can see that the stakeholders are very important people in the organization. Their influence is very powerful as it the one which either led to the success or the failure of the organization. References Corperate Finance Institute. (2019). Stakeholder.
