your browser does not know what an hftp file system is so it wont work. If you use WebHDFS it has rest api's that you can use to read data from hdfs. I would suggest look at those and try them out.

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...

Re: Accessing image files from hadoop to jsp
Posted by Arpit Gupta <ar...@hortonworks.com>.
your browser does not know what an hftp file system is so it wont work. If you use WebHDFS it has rest api's that you can use to read data from hdfs. I would suggest look at those and try them out.

Here's one...
Write a Java program which can be accessed on the server side to pull the picture from HDFS and display it on your JSP.

You should never expose internal host names in the Javascript/HTML.
The flow can be
Browser --> Tomcat --(REST, HDFS Client)--> HDFS
Your web app can make REST requests to HDFS and you could use JAX-RS impl
for REST talk in your web app.
I must warn that user experience will suffer by any of these approaches.
You need some sort of caching solution on top of these proposals.

I'd say yes. Use either WebHDFS (requires client to be able to access
all HDFS nodes) or HttpFS (acts as a gateway if your client can't
access all HDFS nodes) via their REST APIs.
