Subject [jira] [Commented] (HIVE-5122) Add partition for multiple partition ignores locations for non-first partitions
Date Fri, 13 Sep 2013 19:17:51 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13766837#comment-13766837
] 

Thejas M Nair commented on HIVE-5122:
-------------------------------------

Just for the record, the AST for the plan without this fix clearly shows the problem (the
location 'A' of first partition is associated with different partitions) - 
{code}
hive> explain ALTER TABLE add_part_test ADD IF NOT EXISTS           
    > PARTITION (ds='2010-01-01') location 'A'
    > PARTITION (ds='2010-02-01') location 'B'
    > PARTITION (ds='2010-03-01')
    > PARTITION (ds='2010-04-01') location 'C';
OK
ABSTRACT SYNTAX TREE:
  (TOK_ALTERTABLE_ADDPARTS add_part_test TOK_IFNOTEXISTS (TOK_PARTSPEC (TOK_PARTVAL ds '2010-01-01'))
(TOK_PARTITIONLOCATION 'A') (TOK_PARTSPEC (TOK_PARTVAL ds '2010-02-01')) (TOK_PARTITIONLOCATION
'A') (TOK_PARTSPEC (TOK_PARTVAL ds '2010-03-01')) (TOK_PARTITIONLOCATION 'A') (TOK_PARTSPEC
(TOK_PARTVAL ds '2010-04-01')) (TOK_PARTITIONLOCATION 'A'))
