Subject [jira] [Updated] (HIVE-14376) Schema evolution tests takes a long time
Date Wed, 10 Aug 2016 01:09:21 GMT


Prasanth Jayachandran updated HIVE-14376:
    Attachment: HIVE-14376.1.patch

This patch also removes all schema_evol* files from MiniTez. Schema evolution code path should
not be dependent on the engine. MiniTez tests took 1.5 hrs on my laptop but MiniLlap took
only 14 mins. It also removes the explicit order by from the queries.

> schema_evol_* tests (14 tests) takes 47 mins in tez, 40mins in TestCliDriver. Same set
of tests are added to llap as well in HIVE-14355 which will some more time. Most tests uses
INSERT into table which can be slow and is not needed. Even some individual tests takes about
5 mins to run.
