-------------------------------
Summary: 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
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.
