-----------------------------------------
Hi [~wangda]
"ENABLE_DECENTRALIZED_NODELABEL_CONFIGURATION" is fine and will work on that.
And will first focus on NM stuffs and ResourceTracker changes in RM. But
currently i have NodeLabelProvider as service (as per your earlier comments )
and is part of NodeStatus updater, so planning to have some dummy Service which
doesn't give any node labels and is static,
> Allow admin specify labels in each NM (Distributed configuration)
