Project: Hadoop HDFS
Issue Type: Improvement
Components: balancer & mover
Affects Versions: 2.6.0

Adjust the default values to better support the current level of customer host
and network configurations.
Increase the default for property {{dfs.datanode.balance.bandwidthPerSec}} from
1 to 10 MB. Apply to DN. 10 MB/s is about 10% of the GbE network.

threads is 4096. The default number of balancer mover threads is 1000.
