> 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
>
> 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.
