Hello Sir, I am doing mtech in iiit hyderabad and in our project we have similar requirement of accessing the hdfs from apache server(tomcat) directly, Can you please explain how to access the same with some example, probably the same you modified,Does it require hadoop installation directory to sit on the same machine or just jars and config file copying would do.
