Subject [jira] Created: (HDFS-797) TestHDFSCLI much slower after HDFS-265 merge

TestHDFSCLI much slower after HDFS-265 merge
--------------------------------------------

                 Key: HDFS-797
                 URL: https://issues.apache.org/jira/browse/HDFS-797
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions: 0.21.0, 0.22.0
            Reporter: Todd Lipcon


After the merge of HDFS-265 into trunk, TestHDFSCLI takes much longer to run (>10min, got
tired of waiting). Changing dataQueue.wait(1000) to dataQueue.wait(10) on line 2708 speeds
up the test back to its original performance. This isn't a fix, but displays the issue - somehow
the thread isn't getting properly interrupted. In general this probably represents a performance
regression for the exit of all HDFS writers (most noticeable in CLI tools)
