However, this means that you cannot bootstrap a standby when the active NN is in safe mode -- i.e you have to start the whole cluster before you can bootstrap a new standby. This makes the workflow to convert an existing cluster to HA more complicated. We should allow BootstrapStandby to work even when the NN is in safe mode. -- This message is automatically generated by JIRA.
