Subject [jira] [Commented] (CRUNCH-156) Allow support for killing MRPipelines
Date Thu, 28 Feb 2013 02:47:13 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13589123#comment-13589123

Chao Shi commented on CRUNCH-156:
---------------------------------

When I'm using the new interface for my prototype, I feel weird that caller has to catch InterruptedException
and ExectuionException (which are thrown by Future#get) as well as check PipelineResult. In
fact, Pipeline#run throws no exceptions.

In short, the problem is that cancelation is reported as exceptions but failures are error
code. I think it would be nice to have a unified approach.
