Subject [jira] Created: (HIVE-1305) add progress in join and groupby
Date Tue, 13 Apr 2010 21:31:50 GMT
add progress in join and groupby
--------------------------------

                 Key: HIVE-1305
                 URL: https://issues.apache.org/jira/browse/HIVE-1305
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Namit Jain
            Assignee: Paul Yang
             Fix For: 0.6.0


The operators join and groupby can consume a lot of rows before producing any output. 
All operators which do not have a output for every input should report progress periodically.
Currently, it is only being done for ScriptOperator and FilterOperator.
