-----------------------------------
Summary: Use default doesnot work in Hive 1.2.1
Key: HIVE-12943
URL: https://issues.apache.org/jira/browse/HIVE-12943
Project: Hive
Issue Type: Bug
Components: Database/Schema
Affects Versions: 1.2.1
Reporter: Kashish Jain
Fix For: 1.3.0, 1.2.2, 1.2.1
"USE Default" does not work with the latest hive 1.2.1
The message is
"
Cannot recognize input near 'default' '<EOF>' '<EOF>' in switch database
statement; line 1 pos 4
NoViableAltException(81@[])

"
According to my analysis this may be due to the removal of "KW_DEFAULT" keyword
from the grammar of Hive parser according to the bug
https://issues.apache.org/jira/browse/HIVE-6617
Adding the KW_DEFAULT keyword back to the HiveParser.g, HiveLexer.g and
Identifier.g and It worked. Wish to push it to apache-hive
