Date Wed, 17 Jul 2013 19:21:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8939?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13711499#comment-13711499

stack commented on HBASE-8939:
------------------------------

Here is test I found hung this morning:

{code}
"pool-1-thread-1" prio=10 tid=0x00007f1af0481000 nid=0x3a9f waiting on condition [0x00007f1aec2ae000]
   java.lang.Thread.State: TIMED_WAITING (sleeping)
        at java.lang.Thread.sleep(Native Method)
        at org.apache.hadoop.hbase.client.HBaseAdmin.deleteTable(HBaseAdmin.java:617)
        at org.apache.hadoop.hbase.HBaseTestingUtility.deleteTable(HBaseTestingUtility.java:1270)
        at org.apache.hadoop.hbase.master.TestAssignmentManagerOnCluster.testSSHWhenDisablingTableRegionsInOpeningOrPendingOpenState(TestAssignmentManagerOnCluster.java:484)
{code}

Eventually all retries were exhausted and the test went away.

Let me add timeouts to all tests in this class.
