Sergey Shelukhin updated HIVE-18097:
------------------------------------
Description:
We may add an option to move triggers: "on full kill/ignore/delay kill".
The former will kill the query if the dest is full.
The ignore one would not perform the move... The thinking is that admin would
add another trigger to kill queries after some time (e.g. - move after 10s,
kill after 30s), and thus give slow/large queries a grace period in case dest
is full so they cannot gracefully release the capacity.
It's possible to add a third option - "delay kill", where we would ignore the
move, but kill the query if someone requests capacity and the pool is full.
Note that none of these require oversubscription; oversubscription is a pain to
track.
