> RegionServers do reportForDuty on startup to tell Master they are available. 
> If Master is initializing, and especially on a big cluster when it can take a 
> while particularly if something is amiss, the log every three seconds is 
> annoying and doesn't do anything of use. Do backoff if fails up to a 
> reasonable maximum period. Here is example:
> {code}
> 2018-09-06 14:01:39,312 INFO 
> org.apache.hadoop.hbase.regionserver.HRegionServer: reportForDuty to 
> master=vc0207.halxg.cloudera.com,22001,1536266763109 with port=22001, 
> startcode=1536266763109
> 2018-09-06 14:01:39,312 WARN 
> org.apache.hadoop.hbase.regionserver.HRegionServer: reportForDuty failed; 
> sleeping and then retrying.
> ....
> {code}
> For example, I am looking at a large cluster now that had a backlog of 
> procedure WALs. It is taking a couple of hours recreating the procedure-state 
> because there are millions of procedures outstanding. Meantime, the Master 
> log is just full of the above message -- every three seconds...
