Subject [jira] Updated: (HADOOP-3743) -libjars, -files and -archives options do not work with 0.18
Date Tue, 15 Jul 2008 12:51:31 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3743?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amareshwari Sriramadasu updated HADOOP-3743:
--------------------------------------------

    Attachment: patch-3743.txt

Here is a patch doing the following:

1. Adds org.apache.hadoop.mapred.JobShell and org.apache.hadoop.mapred.TestJobShell
2. Adds the static Configuration in JobClient
3. Parsing in JobShell is removed as is not necessary. Because JobShell implements Tool and
ToolRunner does the parsing for it. So, JobShell is used to set the static config for JobClient
for the applications that doesnt implement ToolRunner.

bq. but we make it pass the original arguments strings to runJar.
We cannot send all the remaining arguments to RunJar, because RunJar expects the first argument
to be the MainClass if there is no MainClass in the manifest.

A warning is printed in JobClient if _mapred.used.genericoptionparser_ is not set to _yes_
And also applications that implement ToolRunner, but use JobShell for -libjars or -files or
-archives are warned.

Added earlier usage documentation patch again.

> I am not sure how to get -libjars and -files working with 0.18. I tried all the options
but cannot get it runnning. I am filing this as a blocker until we find out that its not broken.
-- in that case we need to update the docs with an example to say how it works.
