Hello,

I am a hadoop newbie and I have 2 questions.

I followed Hadoop standalone mode testing.
I got error message from Cygwin terminal  like file permission error.
I checked out mailing list and changed the part in RawLocalFileSystem.java but not working.
Still I have file permission error in the directory:   c:/tmp/hadoop../mapred/staging...
I followed instruction about Pseudo-Distributed operation.
Ssh is OK and namenode -format is OK.
But it did not return any results and the processing is just halted.
The Cygwin console scripts are

-----
$ bin/hadoop jar hadoop-examples-*.jar grep input output 'dfs[a-z.]+'
12/02/09 14:25:44 INFO mapred.FileInputFormat: Total input paths to process : 17
12/02/09 14:25:44 INFO mapred.JobClient: Running job: job_201202091423_0001
12/02/09 14:25:45 INFO mapred.JobClient:  map 0% reduce 0%
-----

Any help pls.
Thanks.

Hi,
Just make sure both task tracker and data node is up. Go to localhost:50030
and see is it shows no.of nodes equal to 1?

Hello

Can you please tell which version of Hadoop you are using and also

Does your error matches with below message?

Failed to set permissions of path:
file:/tmp/hadoop-jj/mapred/staging/jj-1931875024/.staging to 0700

Thanks
