---------------------------------

             Summary: CacheAdmin operations not supported with viewfs
                 Key: HDFS-5567
                 URL: https://issues.apache.org/jira/browse/HDFS-5567

          Components: caching
    Affects Versions: 3.0.0

On a federated cluster with viewfs configured, we'll run into the following error when using CacheAdmin commands:

{code}
bash-4.1$ hdfs cacheadmin -listPools
Exception in thread "main" java.lang.IllegalArgumentException: FileSystem viewfs://cluster3/ is not an HDFS file system
