> --------------------------------------

> 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, 1.2.1, 1.2.2
>
>
> "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@[])
> at
> org.apache.hadoop.hive.ql.parse.HiveParser_IdentifiersParser.identifier(HiveParser_IdentifiersParser.java:11577)
> at
> org.apache.hadoop.hive.ql.parse.HiveParser.identifier(HiveParser.java:46055)
> "
> 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
