> Key: HDFS-6456
> URL: https://issues.apache.org/jira/browse/HDFS-6456
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: nfs

> Reporter: Yesha Vora
> Assignee: Abhiraj Butala
> Fix For: 2.6.0

> 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.
