[dengzhhu653]

Hello Community, 




As you have noticed, we are going to propose the next 4.0.1 release on top of 
4.0.0, with some

critical bug fixes and improvements [1]. As of now we are putting the label 
"hive-4.0.1-must" on the tickets

and we plan to make sure those get c-picked to branch-4.0 [2]. Please suggest 
other important fixes that can be 

included in this release if any.




We will get this minor release out as soon as possible once all the tickets 
marked with "hive-4.0.1-must" get resolved and tested.

Memory status chek on HashTableSinkOperator

[dengzhhu653]

Hi all


 When reading the codes of HashTableSinkOperator,  I am confused why do we 
monitor memory usage only when the mapjoin key has never been seen before. If 
the mapjoin keys are much less than the table rows, there is a chance that the 
HashTableSinkOperator will never check the memory,  as the rowContainer mapping 
by the incoming join key should be not null at all. In this case, the 
MapRedLocalTask catches OOM exception and crashes down the hiveserver2 when 
running in the same process.
Any insight on this?


Thanks
