Subject [jira] [Commented] (HIVE-1107) Generic parallel execution framework for Hive (and Pig, and ...)
Date Tue, 31 Jul 2012 17:48:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13425957#comment-13425957
] 

Ahmed Radwan commented on HIVE-1107:
------------------------------------

I wanted to point out that there is work on Yarn to add a new Workflow Application Master
(See MAPREDUCE-4495). It'd be helpful for the Hive community to look into that and provide
early feedback. I am envisioning such WorkFlow Application Master can be used by projects
like Hive, Pig, etc. so they'll share a common workflow engine.

> Pig and Hive each have their own libraries for handling plan execution. As we prepare
to invest more time improving Hive's plan execution mechanism we should also start to consider
ways of building a generic plan execution mechanism that is capable of supporting the needs
of Hive and Pig, as well as other Hadoop data flow programming environments.
