I updated the patch to reflect the comment, and added {{FILESTATUS}} operation. bq. I'm also unclear why {{StringEncoder}} is required. It is required because the type of the json content is {{String}}. > 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.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
