Re: Accessing image files from hadoop to jsp

Thanks a ton guys for showing the right direction.... i was so wrong with
hftp, will try out web hdfs,is hdfs FUSE  mount a good approach by using
that i will have to just mount my existing local java uploads in to hdfs
but can i access Har files using this or will i have to create a symlink
for acessing HAR's...
