Data Eng Weekly

Hadoop Weekly Issue #209

19 March 2017

Some big product announcements at Strata + Hadoop World, a number of open-source project releases, and several great technical posts all make for a great issue this week.


Uber has open-sourced Hoodie, their library for incremental processing on Hadoop with Spark. Somewhat reminiscent of early MPP databases, Hoodie supports a read-optimized view of data (using Parquet) and a hybrid view that combines columnar with row-based (Avro) data. The read optimized store can be used for incremental processing while the hybrid view supports realtime query. In either case, Hoodie does quite a bit of heavy lifting to support updates in addition to inserts—the introductory post describes the ingest path in detail.

Docker containers aren't supposed to add much overhead, but it's good to see benchmarking results that prove the case. BlueData put their BlueData EPIC, which runs Hadoop in Docker containers, up against bare-metal Hadoop on the BigBench benchmark. BlueData has some proprietary technology (IOBoost and DataTap) prevent this from being an apple to apple comparison, but it still shows promise for the future of Big Data in Docker.

The 0.6.0 release of Apache Beam adds a python SDK. The introductory post gives a brief intro on how to get started with the new SDK and provides an example pipeline for estimating the value of pi.

The Morning Paper covers another post from the FAST conference, this week on Apache Omid (incubating). Omid is a transaction layer atop of Apache HBase that was originally built at Yahoo. The post describes the architecture, gives a high-level-overview of the transaction model (and how the client interacts), describes the model for high availability, and more.

This post shows how to use Rstudio with Amazon Athena to query data in S3.

SiliconANGLE has an interview with Holden Karau on the future of Spark. There's a video of the ~15 minute interview and an excerpt about how Spark's MLlib's local mode might be useful for applying machine learning models on devices for IoT applications.


Hortonworks has announced that they'll be brining major revisions of their platform to cloud platforms before releasing it for on-premise.

MapR has introduced a new product called MapR Edge, which is a scaled down version of the MapR platform that can do simple operations on data closer to the source. It's specifically aimed at IoT use cases, and it has a bandwidth-awareness feature for delivering data of unreliable or slow connections.

Based on their acquisition, Cloudera is launching the Cloudera Data Science Workbench, which is somewhat like a jupyter or zeppelin notebooks. There's an enterprise take on the system, though, in that it focuses on security and compliance as well as reproducibility.

Microsoft had a bunch of announcements at Hadoop Summit. Among them, they announced that they've built a Spark connector for DocumentDB, which is their distributed data store that supports SQL and is compatible with the MongoDB query interface. They also announced improved security support for Hive's LLAP (via HDP 2.6) and Spark, a 99.9% SLA for Apache Spark 2.1 on Azure HDInsight, improved streaming support from Spark to the Azure Event Hubs, and more.

The second annual Phoenixcon is taking place on June 13th (the day after HBaseCon). It takes place 10:30-6pm at the Salesforce San Francisco office.

Slides and videos from many presentations given at the Spark Summit East, which was just over a month ago in Boston, have been posted online.


Version 2.6.1 of the Luigi workflow engine was released. The new version includes some updates and bug fixes as well as new support for running jobs via Kubernetes.

Apache Drill 1.10.0 came out this week. It adds a new 'create temporary table as..' command, improved support for timestamps in Parquet files, better fault tolerance over JDBC, support for Kerberos authentication, and more.

In addition to the Python SDK support, this week's Apache Beam release adds support for Apache HBase, improved support for the Beam model in runner implementations, and more.

Version 4.1 of the Cask Data Application Platform was released. The Cask blog has a post on the major improvements, including fine-grained secure impersonation, hot-cold replication, and improved user experience.

This project provides an example template for running Kafka on OpenShift/Kubernetes.

Version 0.2.13 of scio, the scala API for Apache Beam / Google Cloud Dataflow, was released. There are some performance improvements and bug fixes in the release. There's also a beta of version 0.3.0, which is the release in which scio moves from the Dataflow Java SDK to Apache Beam.
