tanishqchugh updated HIVE-28396:
--------------------------------
Description:
Increasing the tez container & AM memory sizes to 256 to address the occurring
OOM issues.
Increase in the sizes causes 3 qtests to fail: mm_all.q, mm_dp.q,
groupby3_map_multi_distinct.q . Analyze the failures and fix them.
Analysis:
*groupby3_map_multi_distinct Analysis:*
We had increased the tez container size from 128 to 256mb to address OOM
errors. Now this qtest has a property - {{set hive.map.aggr=true;}} . If this
property is set to true, a background check runs first named -
{{{}checkMapSideAggregation(){}}}, to verify that there is enough space
available to store the hash table that would be required in order to do this
aggregation. The allotted space for this aggregation is half of container size
and with half of 128mb, it was not enough to store this generated table, but
with half of 256mb, now it is sufficient to store this table and hence map side
aggregation happens. With this aggregation, the hashes for only these 307
distinct rows out of 500 rows are generated and stored and duplicate rows are
mapped to this hashes. Thus, the change in statistics which is expected.

*mm_all Analysis:*
We had increased the tez container size from 128 to 256mb to address OOM
errors. Now, total memory allocated to LLAP daemon is 4096mb and with each
container size increased to 256 mb, available slots = 4096/256 = 16
With increased container size, split size increases and thus each task have
higher resources. Due to this, each task computes larger number of rows and
corrresponds to one hive side file each. The amount of data processed remains
the same, just the amount of data processed by each task increases. Thus only
16 hive files are generated.
