Daryn Sharp commented on HDFS-3255:
-----------------------------------
A manual test would be to run a job with multiple input paths. {{DFSClient}}
logs an info message when a token is fetched, so log should show only one token
retrieved.
> HA DFS returns wrong token service

> {{fs.getCanonicalService()}} must be equal to
> {{fs.getDelegationToken(renewer).getService()}}. When HA is enabled, the DFS
> token's service is a logical uri, but {{dfs.getCanonicalService()}} is only
> returning the hostname of the logical uri.
