[jira] [Created] (MAPREDUCE-5005) TestProcfsProcessTree#testProcessTree() doesn't wait long enough for the process to die

Karthik Kambatla created MAPREDUCE-5005:
-------------------------------------------

             Summary: TestProcfsProcessTree#testProcessTree() doesn't wait long enough for the process to die
                 Key: MAPREDUCE-5005
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5005
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 2.0.2-alpha
            Reporter: Karthik Kambatla


TestProcfsProcessTree#testProcessTree fails occasionally with the following stack trace

{noformat}
Stack Trace:
junit.framework.AssertionFailedError: expected:<false> but was:<true>
        at org.apache.hadoop.util.TestProcfsBasedProcessTree.testProcessTree(TestProcfsBasedProcessTree.java)
{noformat}

kill -9 is executed asynchronously, the signal is delivered when the process comes out of the kernel (sys call). Checking if the process died immediately after can fail at times.
