Hi Team, In case of LLAP every executors can have different memory usage and there is no guard on the memory usage of these executors. For some operators like MAP-JOIN, GROUP-BY etc in llap we have done memory restrictions (Eg: on hash-table) as part of HIVE-15503, HIVE-16546, HIVE-15508.
1) Like in case of MAP-JOIN and GROUP-BY operators, does all the operators have memory restrictions in case of LLAP? 2) If not, does it mean LLAP daemon can go OOM? Thanks!
