Strata Standards Stories: Different Stores For Different Chores

Has HDFS joined MapReduce in the emerging “legacy Hadoop project” category, continuing the swap-out of components that formerly answered the question “what is Hadoop?” Stores for data were certainly a focus at Strata/Hadoop World in NY, O’Reilly’s well-run, well-attended, and always impactful fall event. The limitations of HDFS, including its append-only nature, have become inconvenient enough to push the community to “invent” something DBMS vendors like Oracle did decades ago: a bypass. After some pre-event leaks about its arrival, Cloudera chose its Strata keynote to announce Kudu, a new columnstore written in C++, bypassing HDFS entirely. Kudu will use an Apache license and will be submitted to the Apache process at some undetermined future time.


Hadoop Projects Supported By Only One Distribution

The Apache Software Foundation has succeeded admirably in becoming a place where new software ideas are developed: today over 350 projects are underway. The challenges for the Hadoop user are twofold: trying to decide which projects might be useful in big data-related cases, and determining which are supported by commercial distributors. In Now, What is Hadoop? And What’s Supported? I list 10 supported by only one: Atlas, Calcite, Crunch, Drill, Falcon, Kite, LLAMA, Lucene, Phoenix and Presto. Let’s look at them a little more.


Strata Spark Tsunami – Hadoop World, Part One

New York’s Javits Center is a cavernous triumph of form over function. Giant empty spaces were everywhere at this year’s empty-though-sold-out Strata/Hadoop World, but the strangely-numbered, hard to find, typically inadequately-sized rooms were packed. Some redesign will be needed next year, because the event was huge in impact and demand will only grow. A few of those big tent pavilions you see at Oracle Open World or Dreamforce would drop into the giant halls without a trace – I’d expect to see some next year to make some usable space available.

So much happened, I’ll post a couple of pieces here. Last year’s news was all about promises: Hadoop 2.0 brought the promise of YARN enabling new kinds of processing, and there was promise in the multiple emerging SQL-on-HDFS plays. The Hadoop community was clearly ready to crown a new hype king for 2014.

This year, all that noise had jumped the Spark.
