Xieming Li commented on HADOOP-16753:
-------------------------------------
[~aajisaka], Thank you for your comments.
Since we are currently using _hdfs haadmin -transtionTo\{Active, Standby,
Observer}_ and _-faileover_ to manage HDFS states. Therefore, moving
"-transitionToObserver,-failover" from HAAdmin.java to DFSAdmin.java will cause
a situation where a superclass(HAAdmin) referencing the content in its
subclass(DFSAdmin).
Thus, I think it might be a good idea to keep them as they are.
