> Currently, Pig reuses AMs via TezSession, but they are not shut down when Pig exits. There are two problems that I noticed with this-
> # Tez jobs are not marked as finished until TezSessions are expired after timeout. Since they occupy task slots, it blocks submitting jobs.
> # ant clean test-tez leaves orphan processes (DAGAppMaster).
> Ideally, TezSession should be kept alive while Pig runs but tore down when Pig exits.
