This is not the best behavior -- for example, in > the case of HA, if ZK goes down, we would like the current state to be > maintained, rather than causing either NN to abort. When the ZK clients are > able to reconnect, they should sort out the correct leader based on the > normal locking schemes. -- This message is automatically generated by JIRA.
