Subject [jira] Created: (HIVE-1567) increase hive.mapjoin.maxsize to 10 million

increase hive.mapjoin.maxsize to 10 million

                 Key: HIVE-1567
                 URL: https://issues.apache.org/jira/browse/HIVE-1567
             Project: Hadoop Hive
          Issue Type: Improvement
            Reporter: He Yongqiang

i saw in a very wide table, hive can process 1million rows in less than one minute (select
all columns).
setting the hive.mapjoin.maxsize to 100k is kind of too restrictive. Let's increase this to
10 million.
