Description

In doGet Method,
final DFSInputStream in = dfs.open(filename);
final long fileLen = in.getFileLength();
OutputStream os = response.getOutputStream();
Here this lines are present at out side of the try block.
If response.getOutputStream() throws any exception then DFSInputStream will not be closed.So, better to move response.getOutputStream() into try block.
