> 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 ).
