Thanks, data node may not be known. Is it possible to direct url to namenode and namenode handling streaming by fetching data from various data nodes?

A http download option is also provided in the DataNode web-interface (def-port:50075). Use the "streamFile" feature of the same. An example follows. If I have a file called 'results' lying as /user/hadoop/results, I'll do: wget http://hostname.top.dom:50075/streamFile?filename=/user/hadoop/results -O results This will get me the file data in the wget-local file 'results' On Tue, Jun 15, 2010 at 7:12 PM, Jaydeep Ayachit <[email protected]> wrote: > Hello, > > HDFS supports http read-only access to filesystem.
