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.
