--------------------------------
Summary: NFS: NFS server should throw error for invalid entry in
dfs.nfs.exports.allowed.hosts
Key: HDFS-6456
URL: https://issues.apache.org/jira/browse/HDFS-6456
Project: Hadoop HDFS
Issue Type: Bug
Components: nfs
Affects Versions: 2.2.0
Reporter: Yesha Vora
Pass invalid entry in dfs.nfs.exports.allowed.hosts. Use - as separator between
hostname and access permission
{noformat}
<property><name>dfs.nfs.exports.allowed.hosts</name><value>host1-rw</value></property>
{noformat}
This misconfiguration is not detected by NFS server. It does not print any
error message. The host passed in this configuration is also not able to mount
nfs. In conclusion, no node can mount the nfs with this value. A format check
is required for this property. If the value of this property does not follow
the format, an error should be thrown.
