Subject [jira] [Commented] (HIVE-5302) PartitionPruner fails on Avro non-partitioned data
Date Wed, 18 Sep 2013 17:18:54 GMT


Ashutosh Chauhan commented on HIVE-5302:

Secondly, if you look at .xml file changes it clearly shows it will bloat plan with unnecessary
info that is not required at execution time. I really think we should spend more time on getting
your test case to work in less intrusive fashion.

> While updating HIVE-3585 I found a test case that causes the failure in the MetaStoreUtils
partition retrieval from back in HIVE-4789.
> in this case, the failure is triggered when the partition pruner is handed a non-partitioned
table and has to construct a pseudo-partition.
> e.g.
> {code}
>   INSERT OVERWRITE TABLE partitioned_table PARTITION(col) SELECT id, foo, col FROM non_partitioned_table
WHERE col <= 9;
> {code}
