log for invalid separator in allowed.hosts
Yesha Vora created HDFS-6455:
--------------------------------
Summary: NFS: Exception should be added in NFS log for invalid separator in allowed.hosts
Key: HDFS-6455
URL: https://issues.apache.org/jira/browse/HDFS-6455
Project: Hadoop HDFS
Issue Type: Bug
Components: nfs
Affects Versions: 2.2.0
Reporter: Yesha Vora
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.

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