Amareshwari Sriramadasu updated HADOOP-3417:
--------------------------------------------
Attachment: patch-3417.txt
Here is a patch doing the following:
1. Removes the static configuration variable, commandLineConfig from JobClient.
2. Moves the cli parsing from JobShell to GenericOptionsParser. Thus removes
the class org.apache.hadoop.mapred.JobShell .
3. Refactors TestJobShell as TestCommandLineJobSubmission, which tests the
command line options -files, -libjars
4. testshell.ExternalMapReduce class is modified to implement
org.apache.hadoop.util.Tool, sothat it can be run from ToolRunner.
> JobClient should not have a static configuration for cli parsing

> HADOOP-1622 introduced a static configuration variable into JobClient that
> prevents it from being used by multiple threads. Furthermore, the cli
> processing that HADOOP-1622 added should be in the GenericOptionParser
> instead of JobShell so that all of the implementations of Tool can use them.
