Description

HBASE-15519 added a nice feature to show per-user metrics. It needs a bit of work still – see base of HBASE-15519 for notes but in particular, it can spin up lots of threads, more than makes sense  – but currently it is enabled by default. Here we disable it by setting default for hbase.regionserver.user.metrics.enabled to false.
