Subject Re: Unable to setup HDFS sink
Date Mon, 14 Jan 2013 07:04:43 GMT
I was able to write using the same hdfs conf from a different sink.
Also, I can open the MapRed administration page successfully at
http://localhost:50030/jobtracker.jsp So that should indicate that the
hdfs path below is valid right? Any other way to check?

Thanks.
