Subject [jira] [Commented] (HIVE-5856) Templeton service become nonresponsive
Date Mon, 17 Feb 2014 15:44:19 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13903316#comment-13903316

Dave Winters commented on HIVE-5856:
------------------------------------

Last observed case was on HDP 1.3.2 in with Aster 5 client issuing large number of calls from
SQL-H software. Backend meta store is MySQL.

Seems to be mitigated by increasing the service stack and ram setting > 4Gb

Currently the status is being viewed as a possible memory leak issue that is CND.
CND = can not duplicate

This situation pops up in very large tables with partitions (>200) and columns (>300).

> The Templeton service stops responding to requests from clients.
> Service is running, metastore DB is running. Ports are in LISTEN state.
> All appears normal.
> Seems to occur at high request load rates.
> Current work around is to restart services.
> Still investigating and trying to capture one before reset by user/customer.
> Observed in SLES 11sp3 | CentOS and RHEL.
