Subject Meeting notes from the August Hive Contributors Meeting
Date Sat, 28 Aug 2010 09:59:47 GMT
August 8th, 2010

   - Yongqiang He gave a presentation about his work on index support in
   Hive.
      -

      Slides are available here:
      http://files.meetup.com/1658206/Hive%20Index.pptx
      - John Sichi talked about his work on filter-pushdown optimizations.
   This is applicable to the HBase storage handler and the new index
   infrastructure.
   - Pradeep Kamath gave an update on progress with Howl.
      -

      The Howl source code is available on GitHub </hadoop/GitHub> here:
      http://github.com/yahoo/howl
      - Starting to work on security for Howl. For the first iteration the
      plan is to base it on DFS permissions.
   - General agreement that we should aim to desupport pre-0.20.0 versions
   of Hadoop in Hive 0.7.0. This will allow us to remove the shim layer and
   will make it easier to transition to the new mapreduce APIs. But we also
   want to get a better idea of how many users are stuck on pre-0.20 versions
   of Hadoop.
   - Remove Thrift generated code from repository.
      - Pro: reduce noise in diffs during reviews.
      - Con: requires developers to install Thrift compiler.
   - Discussed moving the documentation from the wiki to version control.
      - Probably not practical to maintain the trunk version of the docs on
      the wiki and roll over to version control at release time, so
trunk version
      of docs will be maintained in vcs.
      - It was agreed that feature patches should include updates to the
      docs, but it is also acceptable to file a doc ticket if there is time
      pressure to commit.j
      - Will maintain an errata page on the wiki for collecting
      updates/corrections from users. These notes will be rolled into the
      documentation in vcs on a monthly basis.
   - The next meeting will be held in September at Cloudera's office in Palo
   Alto.
