[jira] [Created] (HIVE-8466) nonReserved keywords can not be used as table alias

cw created HIVE-8466:
------------------------

             Summary: nonReserved keywords can not be used as table alias
                 Key: HIVE-8466
                 URL: https://issues.apache.org/jira/browse/HIVE-8466
             Project: Hive
          Issue Type: Bug
          Components: SQL
    Affects Versions: 0.13.1, 0.13.0, 0.12.0
            Reporter: cw
            Priority: Minor


There is a small mistake in the patch of issue HIVE-2906. See the change of FromClauseParser.g

-    : tabname=tableName (ts=tableSample)? (KW_AS? alias=identifier)?
-    -> ^(TOK_TABREF $tabname $ts? $alias?)
+    : tabname=tableName (props=tableProperties)? (ts=tableSample)? (KW_AS? alias=Identifier)?
+    -> ^(TOK_TABREF $tabname $props? $ts? $alias?)

With the 'identifier' changed to 'Identifier' we can not use nonReserved keywords as table alias.
