Subject [jira] Commented: (HADOOP-1247) Make Hadoop Abacus work with Hadoop Streaming
Date Tue, 24 Apr 2007 17:04:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12491363
] 

Doug Cutting commented on HADOOP-1247:
--------------------------------------

bq. you are causing the abacus class files to be also compiled into the streaming.jar.

Doesn't streaming build a new jar per job, in order to include job-specific executables, etc.
 If so, can't abacus simply be included at that point?

> It will be nice if Hadoop streaming can use Hadoop Abacus.
> This requires to make some changes on StreamJob and StreamMapRed classes so that the
streaming job uses the Abacus reducer/combiner classes, and streaming mapper generates intermediate
data conforming to Hadoop Abacus protocol.
