Hi, Recently I've been focusing on fixing hftp / hsftp / webhdfs / swebhdfs in various set ups. Now we have reached the state that all the above file systems can work in both secure and insecure clusters, and transfer data through both http and https.
Taking a step back, these file systems are very similar, and I'm wondering whether it is a good time to deprecate hftp and hsftp in Hadoop right now. The main reason is that hftp / hsftp only provides a strict subset of functionalities that webhdfs / swebhdfs offer. Notably, webhdfs / swebhdfs support writes and HA which hftp / hsftp do not support. It's more natural to move forward with webhdfs / swebhdfs, keeping both hftp / hsftp around seems introducing more work. Another reason is that webhdfs has been supported since Hadoop 1, thus getting rid of hftp / hsftp does not seem removing any features, even the users are trying to migrate from Hadoop 1 to Hadoop 2. Your ideas are appreciated.
