Subject [jira] [Created] (HADOOP-8894) GenericTestUtils.waitFor should dump thread stacks on timeout

-----------------------------------

             Summary: GenericTestUtils.waitFor should dump thread stacks on timeout
                 Key: HADOOP-8894
                 URL: https://issues.apache.org/jira/browse/HADOOP-8894
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


Many tests use this utility to wait for a condition to become true. In the event that it times
out, we should dump all the thread stack traces, in case the timeout was due to a deadlock.
This should make it easier to debug scenarios like HDFS-4001.
