• Affects Version/s: 0.17.0

Removed the public class org.apache.hadoop.mapred.JobShell.
Command line options -libjars, -files and -archives are moved to GenericCommands. Thus applications have to implement org.apache.hadoop.util.Tool to use the options.

Description

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.
