Subject [jira] [Commented] (HIVE-14181) DROP TABLE in hive doesn't Throw Error
Date Fri, 03 Feb 2017 14:21:51 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14181?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15851538#comment-15851538

Adam Szita commented on HIVE-14181:
-----------------------------------

It is actually the issue in this ticket that if Hive fails to remove data from disk, the Exception
is swallowed and success is reported after drop table command execution. (This then leaves
data on the disk, but removes the Table from HMS)
After my first patch a lot of tests have failed (600+) because of this - a lot of them used
to swallow errors that now got to the surface. Nevertheless I added a new Conf key so that
this stricter drop_table approach can be switched off/on (default being off). This is now
reflected in my 2nd patch ([^HIVE-14181.2.patch])

> drop table table_name doen't throw an error if drop table fails.
> I was dropping a table and my trash didn't have enough space to hold the table but the
drop table command showed success and the table wasn't deleted. But the hadoop fs -rm -r /hive/xyz.db/table_name/
gave an error "Failed to move to trash" because I didnot have enough space quota in my trash.
