What is the difference between the WebHDFS REST API and HttpFS?
If I understand correctly:
Am I correct?
When would be advisable to use one instead of the other?
I have read a article related with your question. following is the link.
WebHDFS vs HttpFs Major difference between WebHDFS and HttpFs: WebHDFS needs access to all nodes of the cluster and when some data is read it is transmitted from that node directly, whereas in HttpFs, a singe node will act similar to a "gateway" and will be a single point of data transfer to the client node. So, HttpFs could be choked during a large file transfer but the good thing is that we are minimizing the footprint required to access HDFS.
