> Project: Hadoop HDFS
> Issue Type: Bug
> Components: nfs

> 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
> {noformat}
> <property><name>dfs.nfs.exports.allowed.hosts</name><value>host1 ro:host2
> rw</value></property>
> {noformat}
> 2. restart NFS server. NFS server fails to start and print exception console.
> {noformat}
> [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'
