Subject [jira] Commented: (MAPREDUCE-1912) [Rumen] Add a driver for Rumen tool
Date Thu, 19 Aug 2010 08:00:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12900206#action_12900206
] 

Amareshwari Sriramadasu commented on MAPREDUCE-1912:
----------------------------------------------------

Some comments:
* In Folder.java, IllegalArgumentException is caught and main returns the error code as IO_ERROR,
is this what you intended? Or do you want to return a different error code?
* Folder.initialize() is already throwing IllegalArgumentException from parse* methods. They
are also ignored without printing any message.
* TraceBuilder.run() is catching Throwable and returning exit code as 0. Do you want return
a different exit code?

> Rumen, as a tool, has 2 entry points :
> - Trace builder
> - Folder
> It would be nice to have a single driver program and have 'trace-builder' and 'folder'
as its options.
