Subject [jira] Updated: (HADOOP-487) misspelt DFS host name gives null pointer exception in getProtocolVersion
Date Mon, 25 Sep 2006 18:27:54 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-487?page=all ]

Sameer Paranjpye updated HADOOP-487:
------------------------------------

    Status: Patch Available  (was: In Progress)

This patch changes the constructor of Connection to throw an UnknownHostException if an unresolved
InetSocketAddress is passed in. Maybe it should take a shot at resolving the address first
since unresolved addresses can be created with InetSocketAddress.createUnresolved?

> It doesn't work.  It throws an exception.  Fair enough.  
> However, it throws a null pointer exception inside $Proxy0.getProtocolVersion, the code
that checks whether we have the right protocol version, rather than giving us any exception
we could understand or taking an exception in code to which we have sources so we have a way
of understanding the problem.
