Subject [jira] Commented: (HDFS-706) Intermittent failures in TestFiHFlush
Date Wed, 14 Oct 2009 22:58:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12765802#action_12765802

Konstantin Boudnik commented on HDFS-706:

The failing tests are one of hFlushFi0[1-3]_a. Test cases failing with the following diagnostics:
FI: hFlushFi02_a, index=1, datanode=
org.apache.hadoop.util.DiskChecker$DiskErrorException: FI: hFlushFi02_a, index=1, datanode=
        at org.apache.hadoop.fi.FiHFlushTestUtil$DerrAction.run(FiHFlushTestUtil.java:55)
        at org.apache.hadoop.fi.FiHFlushTestUtil$DerrAction.run(FiHFlushTestUtil.java:1)
        at org.apache.hadoop.fi.FiTestUtil$ActionContainer.run(FiTestUtil.java:66)

        at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.hflush(DFSClient.java:3515)
        at org.apache.hadoop.hdfs.TestHFlush.doTheJob(TestHFlush.java:112)
        at org.apache.hadoop.hdfs.TestFiHFlush.runDiskErrorTest(TestFiHFlush.java:53)
        at org.apache.hadoop.hdfs.TestFiHFlush.hFlushFi02_a(TestFiHFlush.java:109)
Index of an exception might differ. {{_a}} tests are writing a file where {{write()}} operation
stays within a block boundary. {{write()}} is followed by {{hflush()}} call. 
{{hflush()}} has an injected fault, which throws {{DiskErrorException}} on one of the pipeline's
nodes. If pipeline doesn't exist then the exception won't be thrown. Which was the case for
these tests since the implementation of {{hflush()}}. 

Something has changed apparently.
