RE: Any one can tell me about how to write to HDFS?

[dhruba Borthakur]

There is a dfs shell utility to do this too. Please see if this utility
works on ur cluster. It can be used as follows:

Bin/hadoop dfs -copyFromLocal <localfile> <dfs path>

Please see if it works on you cluster. If it does, then please compare
the method org.apache.hadoop.fs.FsShell.copyFromLocal() with your code.

Thanks,
dhruba
