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:
https://builds.apache.org/job/HBase-1.3/jdk=latest1.7,label=Hadoop/302/consoleText
Results :
Flaked tests:
org.apache.hadoop.hbase.client.TestSnapshotCloneIndependence.testOnlineSnapshotMetadataChangesIndependent(org.apache.hadoop.hbase.client.TestSnapshotCloneIndependence)
Run 1:
TestSnapshotCloneIndependence.testOnlineSnapshotMetadataChangesIndependent:152->runTestSnapshotMetadataChangesIndependent:357
null
Run 2:
TestSnapshotCloneIndependence.testOnlineSnapshotMetadataChangesIndependent:152->runTestSnapshotMetadataChangesIndependent:357
null
Run 3: PASS
Removed it till someone has chance to spend time on it.

> Project: HBase
> Issue Type: Sub-task
> Components: test
> Reporter: stack
>
> 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.
