Akira Ajisaka commented on HADOOP-16753:
----------------------------------------
Thank you, [~risyomei].
In hdfs and hdfs.cmd, 'hdfs haadmin' directly execute DFSHAAdmin class and
HAAdmin class is not referenced from any scripts. Therefore I think we can
safely move the HDFS specific usages into DFSHAAdmin.
