[jira] [Commented] (HIVE-14376) Schema evolution tests takes a long time

    [ https://issues.apache.org/jira/browse/HIVE-14376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15399812#comment-15399812 ] 

Prasanth Jayachandran commented on HIVE-14376:
----------------------------------------------

Actually it gets worse there are 13 more tests for schema evolution on text. Replacing INSERT INTO queries is extremely laborious task. Most q files are >800 LOC. All of the select queries also have order by.

> 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.
