Subject [jira] Commented: (PIG-157) Add types and rework execution pipeline
Date Mon, 12 May 2008 16:42:55 GMT

    [ https://issues.apache.org/jira/browse/PIG-157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596126#action_12596126

Olga Natkovich commented on PIG-157:
------------------------------------

This comment is for LocalJobRunner proposal.

One good thing about independent local mode is that running pig in this mode does not require
hadoop at all which makes it ideal for trying pig out and for building tutorials on top of
it. It is also good becuase it allows us to maintain and test backend independence of Pig.

> This is the tracking bug for the work to add types to pig and rework the execution pipeline.
 Individual components of this work are covered in subtasks.
> Functional and design specs for this work are:
> http://wiki.apache.org/pig/PigTypesFunctionalSpec
> http://wiki.apache.org/pig/PigTypesDesign
> http://wiki.apache.org/pig/PigExecutionModel
> This work is being done on the branch types, since it is large and disruptive, and we
want to be able to do incremental checkins without causing issues for the trunk.
