background:
HDFS uses the NFS Gateway component to mount the file system to the local directory. Refer to the official website tutorial for the specific configuration process .
Run the following mount command:
[root]>mount -t nfs -o vers=3,proto=tcp,nolock,noacl,sync $server:/ $mount_point
Appears: mount.nfs: Connection timed out
solve:
At that time, the NFS Gateway was installed on only one node, and the above problem occurred. Re-installed NFS Gateway on multiple nodes and successfully mounted the HDFS file system to the local directory.
