    Description

      TestProcfsProcessTree#testProcessTree fails occasionally with the following stack trace

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

      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.
