Ivan Andika updated HDDS-14764:
-------------------------------
Description:
HDDS-13890 supports reconfiguring ozone.scm.nodes.<service>, but not
ozone.scm.address.<service>.<node> since reconfiguration framework requires
reconfigurable properties to specified in advance.
We can support to allow fully zero datanode restarts for SCM reconfiguration.
However, this requires two reconfigurations
# ozone.scm.address.<service>.<node>
# ozone.scm.nodes.<service>
If both configurations are changed at the same time, the ordering of the
reconfiguration is not determined can cause unexpected behaviors.
