[jira] [Created] (HADOOP-13709) Clean up subprocesses spawned by Shell.java:runCommand when the shell process exits

Eric Badger created HADOOP-13709:
------------------------------------

             Summary: Clean up subprocesses spawned by Shell.java:runCommand when the shell process exits
                 Key: HADOOP-13709
                 URL: https://issues.apache.org/jira/browse/HADOOP-13709
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Eric Badger
            Assignee: Eric Badger


The runCommand code in Shell.java can get into a situation where it will ignore InterruptedExceptions and refuse to shutdown due to being in I/O waiting for the return value of the subprocess that was spawned. We need to allow for the subprocess to be interrupted and killed when the shell process gets killed. Currently the JVM will shutdown and all of the subprocesses will be orphaned and not killed.
