Subject [jira] [Commented] (HBASE-13065) Increasing -Xmx when running TestDistributedLogSplitting
Date Sun, 22 Feb 2015 02:21:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14331995#comment-14331995

stack commented on HBASE-13065:
-------------------------------

@zhangduo How you think we end up on 32 bit jvm?  We don't do -d32 in args we pass... I checked
the config we pass.  We select 'JDK 1.7 (latest)' though there are a bunch of options. That
'latest' is 1.7.0.25 might indicate that this box has lagged its update.  I could just remove
the 'H?' machines from the list of options which is currently: (ubuntu||Hadoop) &&
!jenkins-cloud-4GB && !H11

I just changed it to (ubuntu||Hadoop) && !jenkins-cloud-4GB && !H11 &&
!H3 to remove H3 though wonder where the 32-bit comes from. No response from my insider just
yet. Hopefully he'll come back with something soon.

Thanks for digging in here.
