>
> Currently, Templeton launcher kills all child jobs (jobs tagged with the
> parent job's id) upon task retry.
> Upon templeton launcher task retry, templeton should reconnect to the running
> job and continue tracking its progress that way.
> This logic cannot be used for all job kinds (e.g. for jobs that are driven by
> the client side like regular hive). However, for MapReduceV2, and possibly
> Tez and HiveOnTez, this should be the default.
