> @jerryshao yes,the problem has been resolved. May I ask another question？I
want to know if the file system can be converted to Hadoop's Distributed
FileSystem, because when I try the following code: `
conf.set("fs.AbstractFileSystem.gvfs.impl","com.datastrato.gravitino.filesystem.hadoop.Gvfs");
conf.set("fs.gvfs.impl","com.datastrato.gravitino.filesystem.hadoop.GravitinoVirtualFileSystem");
conf.set("fs.gravitino.server.uri","http://localhost:8090";);
conf.set("fs.gravitino.client.metalake","metalake_demo"); Path filesetPath =
new Path("gvfs://fileset/test_catalog/hzySchema/example_fileset/"); FileSystem
fs = filesetPath.getFileSystem(conf); DistributedFileSystem dfs =
(DistributedFileSystem) fs;`
>
> an error message will appear
"com.datastrato.gravitino.filesystem.hadoop.GravitinoVirtualFileSystem cannot
be cast to org.apache.hadoop.hdfs.DistributedFileSystem"
@heziyi399 `GravitinoVirtualFileSystem` extends the super abstract class
`FileSystem`, so you cannot cast it to the `DistributedFileSystem` which also
one of the child class for the `FileSystem`.
