liaowenrui commented on HDFS-3203:
----------------------------------

I mean that checkpointer is not start in ha,also  dfs.namenode.checkpoint.txns is not become
effective.

standbyCheckpointer is running in the ha,and it is  running in active namenode and stanby
namenode.


so I have two doubt:
1.dfs.namenode.checkpoint.txns is not used in ha
2.why standbyCheckpointer  is running in active namenode and standby namenode?
