Summary: HFile Recovery/Rewrite Tool
Key: HBASE-7880
URL: https://issues.apache.org/jira/browse/HBASE-7880
Project: HBase
Issue Type: New Feature
Components: HFile
Affects Versions: 0.96.0
Reporter: Matteo Bertozzi
Assignee: Matteo Bertozzi
Priority: Minor
Sometimes is useful to have a tool to migrate files from a new version to an
old version (e.g. convert a new XYZ encoded/compressed file to an old
"uncompressed" format)
also it will be useful to been able to recover an hfile from a corrupted state.
(e.g. trailer missing/broken, ...)
The "user" can provide the information about the file (compression & co) and
try to recover as much as possible from the file by reading data blocks.
