-------------------------------
Summary: TestHASafeMode#testBlocksAddedWhenStandbyIsDown fails
intermittently on Branch2
Key: HDFS-5836
URL: https://issues.apache.org/jira/browse/HDFS-5836
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Mit Desai
This is an intermittent failure. Seems like a JDK7 issue. I did some initial
research and found that the test always fails when it runs the following tests
in order.
{noformat}
testBlocksRemovedBeforeStandbyRestart
testSafeBlockTracking
testBlocksAddedWhileStandbyIsDown
{noformat}
The test fails with the following error
