Subject [jira] [Commented] (HIVE-7616) pre-size mapjoin hashtable based on statistics
Date Tue, 12 Aug 2014 04:59:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14093738#comment-14093738

Lefty Leverenz commented on HIVE-7616:
--------------------------------------

This adds configuration parameter *hive.hashtable.key.count.adjustment* and gives a description
for *hive.hashtable.initialCapacity* (introduced in 0.7.0 by HIVE-1642).

So document *hive.hashtable.key.count.adjustment* and *hive.hashtable.initialCapacity* in
the wiki before 0.14.0 is released.
