[jira] [Comment Edited] (HIVE-7616) pre-size mapjoin hashtable based on statistics

    [ https://issues.apache.org/jira/browse/HIVE-7616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14086792#comment-14086792 ]

Small patch. Tried on minitez and regular q files, seems to work. I am assuming this field will have the same lifecycle as input pos to name map, so there will be no serialization problems.
