-------------------------------------
how do you plan to handle in case of RBF with multiple destinations, and say
the mount point is using RANDOM or SPACE order?
> Support resolvePath() in DistributedFileSystem for federated HDFS
> -----------------------------------------------------------------
>
> Key: HDFS-16159
> URL: https://issues.apache.org/jira/browse/HDFS-16159
> Project: Hadoop HDFS
> Issue Type: Task
> Components: federation
> Affects Versions: 3.3.1
> Reporter: Aihua Xu
> Assignee: Aihua Xu
> Priority: Major
>
> DistributedFileSystem needs to support resolvePath() similar to
> ViewFileSystem since DistributedFileSystem can be used to talk to Router
> FileSystem. The clients like Hive need the functionality to determine the
> physical clusters to choose the data copy vs. move if src and dest are on
> different physical clusters although they are on the same router file system.
> See Hive-24742.
