@dashengju Can you clarify "getProcessTerminationInfoString will be hang
because processErrorStream have no data to read". Which case it might hang ,
looking at the code
https://github.com/apache/incubator-storm/blob/master/storm-core/src/jvm/backtype/storm/utils/ShellProcess.java#L135
If there is no data in processErrorStream it returns empty string.
If possible can you add a unit test. Thanks.
