Subject [jira] Commented: (HIVE-339) [Hive] problem in count distinct in 1mapreduce job with map side aggregation
Date Wed, 11 Mar 2009 22:04:50 GMT

    [ https://issues.apache.org/jira/browse/HIVE-339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12681060#action_12681060
] 

Zheng Shao commented on HIVE-339:
---------------------------------

hive.339.4.patch: 1073:
+   *   Partitioning Key: 
+   *      grouping key if no DISTINCT
+   *      grouping + distinct key if DISTINCT

should be:
+   *   Partitioning Key: 
+   *      random() if no DISTINCT
+   *      grouping + distinct key if DISTINCT

The same is true for line 1158.


Line 1017: Can you add the comment for MERGEPARTIAL?
