Fei Hui commented on HDFS-14961:
--------------------------------
I think the test case it not correct. Doc for ObserverNameNode is that
{quote}
NOTE: the feature for Observer NameNode to participate in failover is not
implemented yet. Therefore, as described in the next section, you should only
use transitionToObserver to bring up an observer and put it outside the
ZooKeeper controlled failover group. You should not use transitionToStandby
since the host for the Observer NameNode cannot have ZKFC running.

Maybe we should create 3 namenodes and test 3rd namenode without zkfc for
observer namenode
