Lin Liu updated HIVE-13382:
---------------------------
    Description: 
Recently we upgraded Hive from 0.13.1 to Hive 1.2.1.
Then we found that one of our production queries that updates the data for a 
multi-level partitioned table using INSERT OVERWRITE becomes dramatically 
slower than in Hive0.13.1 version (e.g. from 2 hours to more than 14 hours and 
slower and slower).
Note that the MR jobs finished pretty quickly, but the move stage took a very 
long time.

Currently we are using Hive 1.2.1 and HIVE-11940 has been applied.

  was:
In our case we execute a query to update the data for a multi-level partitioned 
table. The MR jobs are finished pretty quickly, but the move stage took a very 
long time.

Currently we are using Hive 1.2.1 and HIVE-11940 has been applied.


> Dynamic partitioning for INSERT OVERWRITE Query is slow
