> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs client
> Affects Versions: 0.22.0
> Reporter: Tanping Wang
> Priority: Critical
> Attachments: HDFS-1401.patch

>
> 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
