-----------------------------
Summary: reportForDuty should do backoff rather than retry every 3
seconds (default).
Key: HBASE-21164
URL: https://issues.apache.org/jira/browse/HBASE-21164
Project: HBase
Issue Type: Improvement
Components: regionserver
Reporter: stack
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}
