I started HDFS by running start-dfs.sh (also tried start-all.sh, but makes
no difference).
I was able to create directories by running: haddop dfs -mkdir <dir>
and using the hadoop java api, e.g. getting a FileSystem instance and do:
fs.mkdirs().
While trying to do FileSystem.createNewFile, I get: "Waiting to find target
node:" messages. By stepping into the source code, I see the client could
not connect to the data node.
Thanks for your help.

Hi:
After startind HDFS, I am able to create directories via the Hadoop api
and the shell app.
However I am not able to create a new file: I keep on getting problems
connecting to the data node. (on locahost:50010)
By going to the admin UI, I see Live Datanodes listed to be correct to
be listed: localhost:50010.
And in the data node log, I see the line:
2006-11-24 10:05:07,261 INFO org.apache.hadoop.dfs.DataNode : Opened
server at 50
010
So looks like the data node is alive.
Also, by clocking on the Browse the filesystem link in the admin ui, I
am taken to the address:
http://192.168.1.3:65535/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F
Which is not resolved.
Any suggestions would be greatly appreciated.
Thanks
