Vineet Garg commented on HIVE-20703:
------------------------------------
bq. long executorMem = 4000000000L can be replaced by
OperatorDesc.getMaxMemoryAvailable() which give max memory available per
container (in case of tez) or executor in case of llap.
During compilation getMaxMemoryAvailable() returns zero, perhaps this is set
during execution?
> Put dynamic sort partition optimization under cost based decision
