Gary Helmling commented on HBASE-2146:
--------------------------------------
Not having all the attributes initially available does seem a bit problematic
if you have automated monitoring setup. You're likely to get an
AttributeNotFoundException if you have a process trying to retrieve it before
it's there.
I'll take a shot at pre-registering those metrics. I think we can do it with
the code <-> method name map in HBaseRPC. I'll post a patch for that (and
remove the duplication) shortly.
> RPC related metrics are missing in 0.20.3 since recent changes
