[jira] [Updated] (HDDS-618) Separate DN registration from Heartbeat
[ https://issues.apache.org/jira/browse/HDDS-618?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arpit Agarwal updated HDDS-618:
-------------------------------
Target Version/s: 0.7.0 (was: 0.5.0)
> 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
> Priority: Major
>
> 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.
