I’m guess I’m being very naïve (and relatively new to HDFS). I can’t show too much code, but basically, I’d like to do:
Path myPath = new Path(“hdfs://A.mycompany.com//some-dir”);
Where Path is a hadoop fs path. I think I can take it from there, if that worked... Did you mean that I need to address the namenode with an http:// address?
Thanks!

another configuration file (with B.company in it) using Configuration,
grab a FileSystem obj with that and then go forward. Seems like some
unnecessary overhead though.

Hi -
We have two namenodes set up at our company, say:
hdfs://A.mycompany.com
hdfs://B.mycompany.com
From the command line, I can do:
Hadoop fs –ls hdfs://A.mycompany.com//some-dir
And
Hadoop fs –ls hdfs://B.mycompany.com//some-other-dir
I’m now trying to do the same from a Java program that uses the HDFS
API. No luck there. I get an exception: “Wrong FS”.
Any idea what I’m missing in my Java program??
Thanks,
Frank
