Jing Zhao commented on HDFS-9112:
---------------------------------
Thanks for the new patch, [~anu]! And thanks for the review, [~templedf]!
Besides the comment from [~templedf], maybe we can print out the current value
of {{DFS_NAMESERVICES}} in the error message? Other than this the patch looks
good to me.

> Key: HDFS-9112

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: tools

> In HDFS-6376 we supported a feature for distcp that allows multiple
> NameService IDs to be specified so that we can copy from two HA enabled
> clusters.
> That confuses haadmin command since we have a check in
> DFSUtil#getNamenodeServiceAddr which fails if it finds more than 1 name in
> that property.
