Subject [jira] [Commented] (HIVE-4807) Hive metastore hangs
Date Tue, 02 Jul 2013 20:27:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13698181#comment-13698181

Ashutosh Chauhan commented on HIVE-4807:
----------------------------------------

Couple of questions:
* Could there be a performance implication of this? I know perf is irrelevant if functionality
doesn't work, but it will be comforting to know that BoneCP is not 10x (randomly picked number)
than DBCP.
* If we find (hopefully) that earlier statement is true, than we should just rip off DBCP
and only use BoneCP as default.

>  Hive metastore hangs (does not accept any new connections) due to a bug in DBCP. The
root cause analysis is here https://issues.apache.org/jira/browse/DBCP-398.  The fix is to
change Hive connection pool to BoneCP which is natively supported by DataNucleus.
