Hi Mittra
As far as I knew, "hdfs haadmin -ns" is not availble..(please someone can
correct, If I am wrong..)
Please check following help command for haadmin..
[root@linux bin]# ./hdfs haadmin
No GC_PROFILE is given. Defaults to medium.
Usage: DFSHAAdmin [-ns <nameserviceId>]
[-transitionToActive <serviceId> [--forceactive]]
[-transitionToStandby <serviceId>]
[-failover [--forcefence] [--forceactive] <serviceId> <serviceId>]
[-getServiceState <serviceId>]
[-checkHealth <serviceId>]
[-help <command>]
Example:
if your service id's are like nn1,nn2
then you can try like,, hdfs haadmin -getServiceState nn1.
Thanks & Regards
Brahma Reddy Battula

Subject: unable to use hdfs haadmin -ns <nameserviceId> on HDP2.1 ,
HDFS2.4.0.2.1
hi All,
I wanted to systematically probe and list all my namenode(s) via CLI.
An easier way was to maintain a masters conf file , but I want to
dynamically find the same leveraging the system metadata.
In process of trying to find the same , I tried to use
hdfs haadmin -ns ... but to my dismay the command always returns "Missing
Command" on the console as if I am doing something syntactically wrong.
I know my nameserviceId and I tried both capital letters and all small
(just to be sure to not commit a silly mistake).
Can you please help me in trying to figure out what I am doing wrong here.
