--------------------------------
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.
