misspelt DFS host name gives null pointer exception in getProtocolVersion
-------------------------------------------------------------------------
Key: HADOOP-487
URL: http://issues.apache.org/jira/browse/HADOOP-487
Project: Hadoop
Issue Type: Improvement
Components: dfs
Affects Versions: 0.5.0
Reporter: Dick King
I'm trying to construct a DistributedFileSystem but I have the wrong hostname.
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.
