[jira] [Updated] (HDDS-3667) If we gracefully stop datanode it
would be better to notify scm and recon to unregister
[ https://issues.apache.org/jira/browse/HDDS-3667?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lisheng Sun updated HDDS-3667:
------------------------------
Description:
if you execute `bin/ozone --daemon stop datanode`, datanode would be better if it handle the signal and the stop dn request to scm, then scm update datanode state to dead.
It would be better if you provide a admin cli tool to support remove datanode manually.
{code:bash}
ozone admin datanode remove <UUID>
{code}
was:
if you execute `bin/ozone --daemon stop datanode`, datanode would be better if it handle the signal and send the unregister request to scm, then scm remove this datanode from scm and reply to the datanode to die.
It would be better if you provide a admin cli tool to support remove datanode manually.
{code:bash}
ozone admin datanode remove <UUID>
{code}
