- Specify the port number used by Hadoop mount daemon.
+ By default, the export can be mounted by any client. The value string
+ contains machine name and access privilege, separated by whitespace
+ characters. The machine name format can be a single host, a Java regular
+ expression, or an IPv4 address. The access privilege uses rw or ro to
+ specify read/write or read-only access of the machines to exports. If the
+ access privilege is not provided, the default is read-only. Entries are
separated by ";".
+ For example: "192.168.0.0/22 rw ; host.*\.example\.com ; host1.test.org
ro;".
+ Only the NFS gateway needs to restart after this property is updated.
