Subject [jira] [Updated] (HIVE-14504) tez_join_hash.q test is slow
Date Wed, 10 Aug 2016 22:31:20 GMT


Prasanth Jayachandran updated HIVE-14504:
    Attachment: HIVE-14504.1.patch

This patch removes explicitly setting execution engine to mr. Initially explicit usage of
execution engine is used to check correctness with MR. I reran the test using TestCliDriver
to check correctness with MR. After separation the test now runs <4 mins in Tez and 1m
30s in MR. If both runs parallel this should be much better than what we had before. 

[~sseth] can you please review?

> tez_join_hash.q also explicitly sets execution engine to mr which slows down the entire
test. Test takes around 7 mins.
