[jira] [Created] (HDFS-5193) Unifying HA support in HftpFileSystem, HsftpFileSystem and WebHdfsFileSystem

Haohui Mai created HDFS-5193:
--------------------------------

             Summary: Unifying HA support in HftpFileSystem, HsftpFileSystem and WebHdfsFileSystem
                 Key: HDFS-5193
                 URL: https://issues.apache.org/jira/browse/HDFS-5193
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Recent changes in HDFS-5122 implement the HA support for the WebHDFS client. 
Similar to WebHDFS client, both HftpFileSystem and HsftpFilesystem access HDFS via HTTP, but their current implementation hinders the implementation of HA support.

I propose to refactor HftpFileSystem, HsftpFileSystem, and WebHdfsFileSystem to provide unified abstractions to support HA cluster over HTTP.
