Hadoop Weekly Issue #213

23 April 2017

Some great technical posts this week on Kafka, StreamSets, Flink, and more. And with all the posts on stream processing, there’s a well-timed “Making Sense of Stream Processing” post that offers a taxonomy for streaming projects.

Technical

The Confluent blog has an article that describes three common issues that tend to occur when running an Apache Kafka cluster in production. These are told in a narrative story, and each has its own moral.

Red Pill Analytics has a tutorial that walks through the steps necessary to install and configure StreamSets, with the end goal of copying a CSV file to Amazon S3.

The Rittman Mead blog has an overview of the architectures behind Apache Impala (incubating) and Apache Drill. The post describes the key components (such as impalad and the Drillbit daemon), gives a high-level overview of the query processing mechanism, and provides a comparison between the two engines.

In the data infrastructure ecosystem, the term “streaming” has many different meanings. This post includes a proposal for classifying projects into processing frameworks (like Storm and Spark Streaming), stream processing APIs (such as Apache Beam and Kafka Streams), and streaming data systems (like Flume, NiFi, and StreamSets).

This post describes an effort to introduce modern data infrastructure tools and setup into a big data setup. The system was composed of a custom ETL tool (with a common framework and set of tools to do things like run a Hive query), standardized “edge nodes” for running etl jobs, and JupyterHub for ad hoc analysis.

The Hortonworks blog has an overview of the features that have been added to the Spark HBase Connector over the last year. These include support for Apache Phoenix, connection caching, support for duplicate column families, and a filter optimization by implementing the UnhandledFilters API.

The Cloudera blog has a post with instructions for configuring and running deep learning frameworks (cuDNN, TensforFlowOnSpark, CaffeOnSpark, DL4J and BigDL) with CDH and the Cloudera Data Science Workbench.

The AWS Big Data blog has a tutorial, complete with code on GitHub and cloud formation templates, for running Apache Flink on Amazon EMR to process data from data in Amazon Kineseis and writing outputs to Amazon Elasticsearch. The post includes a number of code snippets to show relevant configuration and key pieces of the Flink application.
