-------------------------------------------
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.
