Ashutosh Chauhan commented on HIVE-14726:
-----------------------------------------
On taking a second look it seems that delete/update statements can also be
affected by wrath of orc buffers. e.g., for the query in test case RS sort and
shuffle key is ROW__ID and partition column is in value of RS. If I understand
correctly in Reducers FileSink operator need to have an orc buffer open for
each partition. This may result in similar OOM cases. However, I am not sure if
its possible to solve that problem through this optimization for delete/update
statement. [~ekoifman] [~prasanth_j] any suggestions?
