Brandon Li commented on HDFS-6456: ---------------------------------- Both comments from [~abutala] and [~yeshavora] make sense. So, basically, the actually problem is "NFS should print error when there is no valid export" regardless the cause (e.g., invalid hostname string, empty value, ...). > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
