Subject [jira] [Commented] (HIVE-11915) BoneCP returns closed connections from the pool
Date Mon, 28 Sep 2015 18:48:06 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14933769#comment-14933769

Sergey Shelukhin commented on HIVE-11915:
-----------------------------------------

wrt log - it's only set for BoneCP.
wrt retries for other pools - I don't think it's a good idea... The exception can easily be
non-recoverable, and this will introduce a delay. We should deal with these on case by case
basis.

> It's a very old bug in BoneCP and it will never be fixed... There are multiple workarounds
on the internet but according to responses they are all unreliable. We should upgrade to HikariCP
(which in turn is only supported by DN 4), meanwhile try some shamanic rituals. In this JIRA
we will try a relatively weak drum.
