      Description

      The error for invalid separator in dfs.nfs.exports.allowed.hosts property should be added in nfs log file instead nfs.out file.

      Steps to reproduce:
      1. Pass invalid separator in dfs.nfs.exports.allowed.hosts

      <property><name>dfs.nfs.exports.allowed.hosts</name><value>host1  ro:host2 rw</value></property>
      

      2. restart NFS server. NFS server fails to start and print exception console.

      [hrt_qa@host1 hwqe]$ ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null host1 "sudo su - -c \"/usr/lib/hadoop/sbin/hadoop-daemon.sh start nfs3\" hdfs"
      starting nfs3, logging to /tmp/log/hadoop/hdfs/hadoop-hdfs-nfs3-horst1.out
      DEPRECATED: Use of this script to execute hdfs command is deprecated.
      Instead use the hdfs command for it.
      
      Exception in thread "main" java.lang.IllegalArgumentException: Incorrectly formatted line 'host1 ro:host2 rw'
      	at org.apache.hadoop.nfs.NfsExports.getMatch(NfsExports.java:356)
      	at org.apache.hadoop.nfs.NfsExports.<init>(NfsExports.java:151)

      	at org.apache.hadoop.hdfs.nfs.nfs3.Nfs3.main(Nfs3.java:59)
      

      NFS log does not print any error message. It directly shuts down.
