[jira] [Created] (HDFS-5978) Create a tool to take fsimage and expose read-only WebHDFS API

Akira AJISAKA created HDFS-5978:
-----------------------------------

             Summary: Create a tool to take fsimage and expose read-only WebHDFS API
                 Key: HDFS-5978
                 URL: https://issues.apache.org/jira/browse/HDFS-5978
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: tools
            Reporter: Akira AJISAKA


Suggested in HDFS-5975.

Add an option to exposes the read-only version of WebHDFS API for OfflineImageViewer. You can imagine it looks very similar to jhat.

That way we can allow the operator to use the existing command-line tool, or even the web UI to debug the fsimage. It also allows the operator to interactively browsing the file system, figuring out what goes wrong.
