Subject [jira] Commented: (HADOOP-2622) Fix -file option in Streaming to use Distributed Cache
Date Tue, 25 Nov 2008 11:27:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650535#action_12650535

Amareshwari Sriramadasu commented on HADOOP-2622:

With HADOOP-3722 and HADOOP-3570, User has -files, -libjars and -archives options for streaming
to add files/jars/archives and libjars are available in client-side classpath also. Moreover,
options -file and -files are confusing to the user now. We can deprecate the use of -file,
and ask them to use -files, -libjars, -archives whichever are necessary.

> The -file option works by putting the script into the job's jar file by unjar-ing, copying
and then jar-ing it again.
> We should rework the -file option to use the DistributedCache and the symlink option
it provides.
