Description

I am converting a secure non-HA cluster into a secure HA cluster. After the configuration and started all the journalnodes, I executed the following commands on the original NameNode:
1. hdfs name -initializeSharedEdits #this step succeeded
2. hadoop-daemon.sh start namenode # this step failed.

So the namenode can not be started. I verified that my principals are right. And if I change back to the secure non-HA mode, the namenode can be started.

The namenode log just reported the following errors and I could not find the reason according to this log:
