SSM v1.3.1

Highlights:

• Asynchronous data copy to S3. New action 'copy2s3' added to copy a file from local Hadoop cluster to S3 buckets. Please refer S3 Supporting for more info.
• Action chain supported. An action chain contains 2 or more actions and these actions are executed sequentially. Failure of one action will cause the whole action chain execution failure. Please refer Section SSM rule examples in SSM Deployment Guide.
• Cmdlet history purging. Two policies supported (number of cmdlets and time-to-live) for cmdlet purging. Please refer Section Performance tuning in SSM Deployment Guide.
• Dynamic enable/disable SmartDFSClient supported. Please refer Section Performance tuning in SSM Deployment Guide.
