Hemanth Yamijala commented on HADOOP-5488:
------------------------------------------
bq. changing the methodCall umbilical.getTask(JVMId) to
umbilical.getTask(JVMId, pid) in Child.java
It seems cleaner to define a new method: umbilical.setProcessHandle(JVMId,
handle). This way we send this information only once per JVM. We can also
handle cases like what happens if this call fails. For e.g., I suppose this
call will be made before the child runs the task, and if this call fails, it
should ideally abort.
> HADOOP-2721 doesn't clean up descendant processes of a jvm that exits cleanly
> after running a task successfully
