Wei Zhou commented on HDFS-11123:
---------------------------------
Hi [~umamaheswararao], thanks for the contribution! After looking at your
patch, I think that [HDFS-11186
|https://issues.apache.org/jira/browse/HDFS-11186] should be done based on this
JIRA, as Active NN and Standby NN can transit to each other dynamically, so
it's better to have this as the base. What's your opinion?

> The idea of this task is to make SPS daemon thread to start/stop dynamically
> in Namenode process with out needing to restart complete Namenode.
> So, this will help in the case of admin wants to switch of this SPS and wants
> to run Mover tool externally.
