[ http://issues.apache.org/jira/browse/HADOOP-487?page=comments#action_12437001 ] Dick King commented on HADOOP-487: ----------------------------------
The way to duplicate the problem is to change the text <property> <name>fs.default.name</name> <value>kry1200.inktomisearch.com:8020</value> <description>The name of the default file system. Either the literal string "local" or a host:port for DFS.</description> </property> in hadoop-site.xml and then launch any hadoop job that doesn't override fs.default.name in its code. -dk > 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 > Assigned To: Sameer Paranjpye > > 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. > -dk -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
