Subject [jira] [Created] (HDFS-11316) TestDataNodeVolumeFailure fails frequently
Date Wed, 11 Jan 2017 12:01:06 GMT
Yiqun Lin created HDFS-11316:
--------------------------------

             Summary: TestDataNodeVolumeFailure fails frequently
                 Key: HDFS-11316
                 URL: https://issues.apache.org/jira/browse/HDFS-11316
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 3.0.0-alpha2
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin
            Priority: Minor


The test {{TestDataNodeVolumeFailure#testUnderReplicationAfterVolFailure}} fails frequently
in recent Jenkins buildings. The stack infos:
{code}
org.apache.hadoop.hdfs.server.datanode.TestDataNodeVolumeFailure.testUnderReplicationAfterVolFailure

java.lang.AssertionError: There is no under replicated block after volume failure
	at org.junit.Assert.fail(Assert.java:88)
	at org.junit.Assert.assertTrue(Assert.java:41)
	at org.apache.hadoop.hdfs.server.datanode.TestDataNodeVolumeFailure.testUnderReplicationAfterVolFailure(TestDataNodeVolumeFailure.java:419)
{code}
We would be better using {{GenericTestUtils.waitFor}} here to wait for the condition being
satisfied.
