Both base line and patch YARN-2162 runs 20 times. Result is in uploaded file test-400nm-200app-2k_NODE_UPDATE.timecost.svg. Please ignore the "Resource Type 0", it is the yarn-2162 patch actually. No obvious performance regression. The patch version even performs a little better due to normal fluctuation. was (Author: yufeigu): Run SLS with 400 nodes, 200 apps, and 2k containers.
