Ah, NPE usually means a code bug, then there is no simple way to fix
it, need to take a deep look on the code :(
Sorry.

Strange, I checked the code, it seems we get NPE on this line
https://github.com/apache/hbase/blob/4d7ce1aac724fbf09e526fc422b5a11e530c32f0/hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterRpcServices.java#L2872
Could you please confirm that you connect to the correct active master
Hi Duo,
To be honest, we only use one master, so there is no way to swap them.
After the attempt throwing the NPE we ran the hbck tool again in which case no
NPE was thrown but also nothing else - the log looked just the one I’ve send
you just without the exception stack trace and nothing more.
