Solutions

1. Check that the path's authority matches one of the namenodes configured in dfs.nameservices / dfs.ha.namenodes.
2. Correct the path hostname/port or fix the HA/federation configuration in hdfs-site.xml.

When it happens

Trigger: Mover invocation when the path's nameservice does not match any nameservice configured in dfs.nameservices.

Common situations: See trigger scenarios.
