> SecondaryNameNode could include the hostname/port in socket connect failures

> Key: HDFS-349
> URL: https://issues.apache.org/jira/browse/HDFS-349
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Steve Loughran
> Priority: Minor
>
> reported on the user mailing list. when the Secondary name node can't connect
> to the default filesystem, it passes up the JVM error, which of course omits
> useful information such as the host and port it is trying to connect to. all
> you see is : java.net.NoRouteToHostException: No route to host , which is
> not usually enough to diagnose problems.
