-----------------------------------
mousom has commented on the revision "HIVE-2907 [jira] Hive error when dropping
a table with large number of partitions".
May I modify the drop_table_failure3.q test itself to do that? That might
serve both purposes.

Can you please make this a separate task Kevin?
Thanks
common/src/java/org/apache/hadoop/hive/conf/HiveConf.java:292 like the *.q
file I added?
metastore/src/test/org/apache/hadoop/hive/metastore/TestHiveMetaStore.java:544
yup
metastore/src/test/org/apache/hadoop/hive/metastore/TestHiveMetaStore.java:1997
my bad. done.
common/src/java/org/apache/hadoop/hive/conf/HiveConf.java:292 i will add both
in *.q files.
metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java:1399 I
thought about it but it's just intuitively does not make sense if we return
'ALL' when 0 is passed.And it might be a very difficult to catch bug for a
client.But, on the other hand, you are right that this change might break
existing clients and that has to be avoided, so I guess I will make this bug a
feature :-)
