Subject [jira] Updated: (HDFS-1401) TestFileConcurrentReader test case is still timing out / failing
Date Tue, 07 Dec 2010 23:17:01 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1401?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konstantin Boudnik updated HDFS-1401:
-------------------------------------

    Attachment: HDFS-1401.patch

At first I have converted the test into JUnit v.4 and it had start passing.
Later I did a number of validation on different machine with and without the patch and it
seems that the test is passing in either case with latest trunk. However, it has been failing
in the latest trunk build on Hudson, so let's see what's gonna happen next morning.

> The unit test case, TestFileConcurrentReader after its most recent fix in HDFS-1310 still
times out when using java 1.6.0_07.  When using java 1.6.0_07, the test case simply hangs.
 On apache Hudson build ( which possibly is using a higher sub-version of java) this test
case has presented an inconsistent test result that it sometimes passes, some times fails.
For example, between the most recent build 423, 424 and build 425, there is no effective change,
however, the test case failed on build 424 and passed on build 425
> build 424 test failed
> https://hudson.apache.org/hudson/job/Hadoop-Hdfs-trunk/424/testReport/org.apache.hadoop.hdfs/TestFileConcurrentReader/
> build 425 test passed
> https://hudson.apache.org/hudson/job/Hadoop-Hdfs-trunk/425/testReport/org.apache.hadoop.hdfs/TestFileConcurrentReader/
