<description>
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.

This directory is used to temporarily save out-of-order writes before
writing to HDFS. For each file, the out-of-order writes are dumped after
they are accumulated to exceed certain threshold (e.g., 1MB) in memory.
One needs to make sure the directory has enough space.
