Subject [jira] Commented: (HIVE-827) increase hive.mapjoin.cache.numrows default value
Date Mon, 14 Sep 2009 05:18:57 GMT

    [ https://issues.apache.org/jira/browse/HIVE-827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12754827#action_12754827

Namit Jain commented on HIVE-827:
---------------------------------

What I meant to say is that there is enough memory on the machines to fit more than 10,000
rows easily - of course, that depends on the row size.
But, based on the mails in the mailing lists, I felt that, a higher default may be better
