Subject [jira] [Updated] (HIVE-8621) Aggregate all small table join data into m x n broadcast variables [Spark Branch]
Date Mon, 27 Oct 2014 23:16:34 GMT

     [ https://issues.apache.org/jira/browse/HIVE-8621?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Suhas Satish updated HIVE-8621:
-------------------------------
    Description: 
The number of broadcast variables that must be created is m x n where
'm' is  the number of small tables in the (m+1) way join and n is the number of buckets of
tables. If unbucketed, n=1

This is a sub-task of map-join for spark 
https://issues.apache.org/jira/browse/HIVE-7613

This can use the baseline patch for map-join
https://issues.apache.org/jira/browse/HIVE-8616
