copyToLocal question

[neeral beladia <ne...@yahoo.com>]

Hi,

I am not sure if this question has been asked. Its more of a hadoop fs question. 
I am trying to execute the following hadoop fs command :

hadoop fs -copyToLocal s3n://<Access Key>:<Secret Key>@<bucket name>/file.txt    
/home/hadoop/workspace/file.txt

When I execute this command directly from the Terminal shell, it works perfectly 
fine, however the above command from code doesn't execute. In fact, it says :

Exception in thread "main" copyToLocal: null

Please note I am using Runtime.getRunTime().exec(cmdStr), where cmdStr is the 
above hadoop command. Also, please note that hadoop fs -cp or hadoop fs -rmr 
commands work fine with source and destination being both Amazon AWS locations. 
In the above command (hadoop fs -copyToLocal) the destination is local location 
to my m/c.

Your help would be greatly appreciated.

Thanks,

Neeral
