Subject [jira] [Commented] (HIVE-2542) DROP DATABASE CASCADE does not drop non-native tables.
Date Fri, 18 May 2012 00:29:02 GMT


Vandana Ayyalasomayajula commented on HIVE-2542:

Hey Ashutosh, 
The arc diff does not seem to pick the moves correctly, so in addition to the above patch,
you will have to execute the following commands while committing.

mkdir hbase-handler/src/test/queries/positive
svn add hbase-handler/src/test/queries/positive
svn mv hbase-handler/src/test/queries/*.q hbase-handler/src/test/queries/positive/
svn mv hbase-handler/src/test/queries/*.m hbase-handler/src/test/queries/positive/
mkdir hbase-handler/src/test/results/positive
svn add hbase-handler/src/test/results/positive
svn mv hbase-handler/src/test/results/*.q.out hbase-handler/src/test/results/positive
svn mv hbase-handler/src/test/results/*.m.out hbase-handler/src/test/results/positive

ant test -Dtestcase=TestHBaseNegativeCliDriver
ant test -Dtestcase=TestHBaseCliDriver

commands run successfully.

> The hive meta store client does not delete the non-native tables during the drop database
<dbname> cascade operation. As a result even though the database is deleted the tables
still exist. This is related to HCATALOG-144. 
> A deeper look at the HiveMetaStoreClient's "dropDatabase" function, tells us that the
function does not utilize the hive meta hooks of the tables in the database for dropping the
non-native tables.
