Subject [jira] [Commented] (HBASE-13065) Increasing -Xmx when running TestDistributedLogSplitting
Date Tue, 24 Feb 2015 05:11:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14334410#comment-14334410
] 

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

I compared precommit and trunk configs.  precommit was jdk7u51.  trunk was 'latest jdk7'.
I set it to 'jdk7u51'.  Precommit had this for args to pass: export MAVEN_OPTS="-Xmx6100M
-XX:-UsePerfData"  and trunk had MAVEN_OPTS="-Xmx3g".  I made trunk have what precommit has.
 I think made the build-1 the same as trunk and precommit too.  Lets see how that does (I
removed the !H3 too).

instead of 1000ms, this is likely due to a long garbage collecting pause and it's usually
bad, see http://hbase.apache.org/book.html#trouble.rs.runtime.zkexpired

> Maybe we should increase the max heap size since this test starts 6 regionservers.
