Akira AJISAKA updated HDFS-5978: -------------------------------- Description: Suggested in HDFS-5975. Add an option to OfflineImageViewer to launch HTTP server that takes fsimage and exposes the read-only version of WebHDFS API for OfflineImageViewer. The server only supports {{LISTSTATUS}} operation and other operations such as {{GETFILESTATUS}} will be added by other JIRAs. 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. was: 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. > 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 > Assignee: Akira AJISAKA > Labels: newbie > Attachments: HDFS-5978.2.patch, HDFS-5978.3.patch, HDFS-5978.4.patch, > HDFS-5978.5.patch, HDFS-5978.patch > > > Suggested in HDFS-5975. > Add an option to OfflineImageViewer to launch HTTP server that takes fsimage > and exposes the read-only version of WebHDFS API for OfflineImageViewer.
