Hi [~wangda] & [~rohithsharma],
Please find the attached patch with the offline discussed modifications

*For Config :*
Currently we are supporting configuration param : "yarn.nodemanager.node-labels.provider.configured-node-labels"
so instead can we have = > yarn.nodemanager.node-labels.provider.configured-node-partition which accepts only single partition and in future we can add yarn.nodemanager.node-labels.provider.configured-node-constraints which can support multiple constraints

*For Script :*
Currently in the patch i am searching for lines starting with "NODE_LABELS:" in script output and labels separated by "," though we currently support only a single Partition per node.
So my suggestion we can currently support for parsing lines starting with "NODE_PARTITION:"  and send the string following this pattern as Node Label. Later in future we can support for  "NODE_CONSTRAINTS:"  and accept multiple constraints for it.
