Subject [jira] [Commented] (HBASE-14678) Experiment: Temporarily disable balancer and a few others to see if root of crashed/timedout JVMs
Date Sat, 24 Oct 2015 21:30:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14972875#comment-14972875

stack commented on HBASE-14678:

I removed hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestSnapshotCloneIndependence.java
from master, branch-1 and branch-1.2. It is failing. Here is example:


Results :

Flaked tests: 
  Run 1: TestSnapshotCloneIndependence.testOnlineSnapshotMetadataChangesIndependent:152->runTestSnapshotMetadataChangesIndependent:357
  Run 2: TestSnapshotCloneIndependence.testOnlineSnapshotMetadataChangesIndependent:152->runTestSnapshotMetadataChangesIndependent:357
  Run 3: PASS

Removed it till someone has chance to spend time on it.

> Looking at recent builds of 1.2, I see a few of the runs finishing with kills and notice
that a JVM exited without reporting back state. Running the hanging test finder, I can see
at least that in one case that the balancer tests seem to be outstanding; looking in test
output, seems to be still going on.... A few others are reported as hung but they look like
they have just started running and are just killed by surefire.
> This issue is about trying to disable a few of the problematics like balancer tests to
see if our overall stability improves. If so, I can concentrate on stabilizing these few tests.
Else will just undo the experiment and put the tests back on line.
