-----------------------------------
Summary: Separate DN registration from Heartbeat
Key: HDDS-618
URL: https://issues.apache.org/jira/browse/HDDS-618
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Hanisha Koneru
Currently, if SCM has to send ReRegister command to a DN, it can only do so
through heartbeat response. Due to this, DN reregistration can take upto 2
heartbeat intervals.
We should decouple registration requests from heartbeat, so that DN can
reregister as soon as SCM detects that the node is not registered.
