Prasanth Jayachandran commented on HIVE-20703:
----------------------------------------------
{quote}During compilation getMaxMemoryAvailable() returns zero, perhaps this is
set during execution?
{quote}
Yes. you are right. This is set in RecordProcessor init which is execution.
Maybe you can copy MemoryInfo class from HIVE-20713 to avoid duplicate. I can
rebase HIVE-20713 after this patch is committed.
