Chen Liang commented on HDFS-14059:
-----------------------------------

Thanks for sharing [~zero45]!

For (1), On a quick glance of the code, it seems if 
\{{dfs.ha.automatic-failover.enabled}} is set to true, manually transition will 
be rejected with that error. Did you have this configured? We don't seem to 
have this.

For (2), I think what you suspect makes a lot of sense. I was getting the same 
error and ended up with adding {{hadoop.security.service.user.name.key}}. 
HDFS-14035 should fix this.
