LGTM

hadoop-hdfs-project/hadoop-hdfs/src/site/markdown/HDFSCommands.md Outdated

If user wants to talk to `hdfs://MyCluster2/`, then they can pass -fs option (`-fs hdfs://MyCluster1/user`)
Since /user was mapped to a cluster `hdfs://MyCluster2/user`, dfsadmin resolve the passed (`-fs hdfs://MyCluster1/user`) to target fs (`hdfs://MyCluster2/user`).
This was users can get the access all hdfs child file systems in ViewFsOverloadScheme.

### Central Mount Table Configurations

To enabled central mount table configuration, we need to configure `fs.viewfs.mounttable.path` in `core-site.xml` with the value as the Hadoop compatible file system directory/file path, where the `mount-table-<versionNumber>.xml` file copied. Here versionNumber is an integer number and need to increase the version number and upload new file in same directory.
