Yeah, just to reinforce what Ted is saying, DO NOT run HDFS's balancer if you use HBase. Doing so will move blocks in such a way as to destroy data locality and negatively impact HBase performance (until a major compaction in HBase is done). On Friday, October 7, 2016, Ted Yu wrote: > For #1, it

For #1, it depends on whether major compaction is disabled. If major compaction is enabled, timing of major compaction would affect the data locality. For #2, no. hdfs rebalance is orthogonal to hbase. For #3, perform major compaction at earliest convenience. On Thu, Oct 6, 2016 at 11:47 PM, Man
