Dear Wiki user,

The "Hive/Development/ContributorsMeetings/HiveContributorsMinutes100913" page has been changed
by CarlSteinbach.

- Carl Steinbach gave a status update on the 0.6 release.  Since plans for documentation migration
have been deferred to the next release, the only remaining issues are completion of the CREATE
DATABASE feature (HIVE-675), metastore VARCHAR precision widening ([[https://issues.apache.org/jira/browse/HIVE-1364|HIVE-1364]]),
and metastore upgrade scripts ([[https://issues.apache.org/jira/browse/HIVE-1427|HIVE-1427]]).
 [[https://issues.apache.org/jira/browse/HIVE-675|HIVE-675]] has already been committed to
trunk and the backport for 0.6 is underway.  Carl is still working on companion feature [[https://issues.apache.org/jira/browse/HIVE-1517|HIVE-1517]],
but unless it is done by Sept 17, we'll drop it from the 0.6 release.  Once a build containing
the remaining features passes all unit tests, we'll post a release candidate and vote on it
(no additional acceptance testing is planned for this release).

  Next, [[https://issues.apache.org/jira/browse/HIVE-1546|HIVE-1546]] (making semantic analysis
pluggable) was discussed.  The Howl team gave an overview of their use case for reusing Hive
DDL processing within Howl's CLI, together with a description of the roadmap for Howl/Hive
project relationship.  Carl raised concerns about potential dependency creep preventing future
Hive refactoring, and Namit Jain proposed reworking the approach to restrict it to pre/post-analysis
hooks (limiting the dependencies exposed) rather than full-blown analyzer pluggability+subclassing.
 It was agreed that the hooks approach was the best course for balancing all of the concerns
and allowing us to achieve the desired project collaboration benefits.  The Howl team also
committed to getting their Howl checkins going into a public repository as soon as possible,
together with setting up continuous integration to track the health of the combination of
Hive+Howl trunks.
