Support a stop command in ShellCommandExecutor -----------------------------------------------
Key: HADOOP-7722 URL: https://issues.apache.org/jira/browse/HADOOP-7722 Project: Hadoop Common Issue Type: Bug Affects Versions: 0.23.0 Reporter: Hitesh Shah Priority: Minor Fix For: 0.23.0 Add a stop function call to Shell so as to either stop the process from getting started if not already done so or destroy the process if it already has started. Context of usage: There can be race conditions when trying to kill an execution as the shell::execute call is blocking and using the getProcess call is not a feasible option as there can be a delay between the execute call and when the process object is actually created ( after which it can be used to kill the running sub-process ). -- This message is automatically generated by JIRA.
