I planned to perform rolling restart from (our variant of) 0.92 to 0.94.0 but found out that some internal changes prevented region server to talk to 0.94.0 master. So I loaded every server with 0.94.0 jar and started a 5 RS cluster. I went through master and RS UI. Performed 'balancer' command in shell.
Didn't do much testing and didn't see issue (therefore no vote). Minor comment: yesterday Lars showed me the new percentile metrics added recently. Since the readings were high, it would be nice to include unit of time in the String form of RegionLoad.
