Harsh, When I trying to readFields as follows:
FileStatus origFStatus[] = ipFs.listStatus( ip ); DataInput dataIp; origFStatus[ 0 ].readFields( dataIp ); I am getting a compilation error "variable dataIp might not have been initialized". How do we initialize it? Is there a direct method by which I can get the read the fields easily. On Mon, Mar 5, 2012 at 7:49 AM, Piyush Kansal <piyush.kan...@gmail.com>wrote: > Thanks Harsh.
