Spark is shaping up as the leading alternative to Map/Reduce for several reasons including the wide adoption by the different Hadoop distributions, combining both batch and streaming on a single platform and a growing library of machine-learning integration (both in terms of included algorithms and the integration with machine learning languages namely R and Python). At AppsFlyer, we’ve been using
Spark is compatible with Hadoop filesystems and formats so this allows it to access HDFS and S3. The Spark build installed on EMR as described at https://github.com/awslabs/emr-bootstrap-actions/tree/master/spark allows the Spark application to access S3 out of the box without any additional configuration needed. For example, if a cluster is created with IAM roles (http://docs.aws.amazon.com/Elast
About Amazon EMR Releases - Amazon EMR
An Amazon EMR release is a set of open-source applications from the big-data ecosystem. Each release comprises different big-data applications, components, and features that you select to have Amazon EMR install and configure when you create a cluster. Applications are packaged using a system based on Apache BigTop, which is an open-source project associated with the Hadoop ecosystem. This guide p

LZO compressed files are commonly used in big data processing. Traditionally with Hadoop MapReduce LZO files are not splittable without first being indexed. Indexing of LZO files can be done using the twitter/hadoop-lzo project. The hadoop-lzo.jar is preinstalled on EMR AMIs at /home/hadoop/share/hadoop/common/lib/hadoop-lzo.jar. Spark provides multiple methods to read in datasets such as .textFil
1. Akira Chiku is an engineer who works on an engineering team. Their requirements include collecting between 10-20GB of data per day from various sources like Hadoop and Hive. 2. Data is collected from sources like Fluentd and parsed using Query String and stored in Hive. It is then processed and visualized. 3. Data can be stored in S3, processed using services like AWS EMR, and visualized in das

Amazon Elastic MapReduce Deep Dive and Best Practices (BDT404) | AWS re:Invent 2013
Amazon Elastic MapReduce Deep Dive and Best Practices (BDT404) | AWS re:Invent 2013 Amazon Elastic MapReduce is one of the largest Hadoop operators in the world. Since its launch four years ago, our customers have launched more than 5.5 million Hadoop clusters. In this talk, we introduce you to Amazon EMR design patterns such as using Amazon S3 instead of HDFS, taking advantage of both long and sh
ものぐさな人の味方・Amazon Elastic MapReduceの続き。今回はApache Pigを動かす、の巻。各種前提は前回と同じ。 AEMインスタンス起動 $ elastic-mapreduce --create --name PIG --alive --num-instances 4 --instance-type m1.small --log-uri s3://<your bucket here>/logs --hadoop-version 0.20 --pig-interactive→Job識別子が返されるのでどこかにコピペしておこう。 ※--pig-interactiveオプションをつけると、AEMインスタンス起動後にPigがインストールされる。 AEMインスタンスにログイン $ elastic-mapreduce --jobflow ジョブ識別子 --ssh -----
