> 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. We should spew less those logs. Here
> is example:
> {code:java}
> 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...
