Subject Re: Tez GC issues perhaps? not sure.

Let us validate that this is due to the TTL GC kicking in and disable the TTL flag & leave
it running for a day.

Better to also verify the Tez logs of sessions hanging along waiting for the ATS to collect
events (look for the last _post log file in the AM logs link).

Yes, but you would lose all the existing history, so not yet - but it will be what you need
to do to get out of the TTL.
