Zhijie Shen updated YARN-378:
-----------------------------

    Attachment: YARN-378_8.patch

Make the patch be restricted in the scope of YARN only. In addition, 
maxAppRetries is set in the environment when launching AM. The global 
maxAppRetries is validated when RM is initiated, if it is non-positive, RM will 
crash. Note that MRAppMaster and TestStagingCleanup have reference to 
YarnConfiguration.RM_AM_MAX_RETRIES, which has been changed to 
YarnConfiguration.RM_AM_MAX_ATTEMPTS. Therefore, the build of mapreduce will be 
broken temporally.
                
> ApplicationMaster retry times should be set by Client
