I am wondering if there is a general way how to determine what YARN applications were started by some application and vice-versa if some YARN application was started by some other.
My use case is Oozie and sqoop where Oozie runs some launchers that in turn start some MR jobs to do the actual ingest. It is possible to browse through the logs to get ID of spawned application, but keep thinking that there should be some better way how to do it. This kind of relation must be stored somewhere, since when the Oozie workflow is killed all child processes are killed as well almost immediately.
Thanks for any hints,
