The following commit(s) were added to refs/heads/master by this push:
new 0bf6ee1 HBASE-27980 Sync the hbck2 README page and hbck2 command help
output (#134)
0bf6ee1 is described below
commit 0bf6ee19352bfd597bbe3d4325017a0fceaef6b9
Author: Nihal Jain <nihaljain...@gmail.com>
AuthorDate: Sun Aug 20 23:58:37 2023 +0530
HBASE-27980 Sync the hbck2 README page and hbck2 command help output (#134)
- Sync the readme and help output, both ways and finally paste help output
in readme file
- Fix errors and formatting issues, here and there
- Fix ordering of new commands in code, as we follow alphabetical ordering
of commands
- Also syncing readme with help output, exposes new commands like
`recoverUnknown` and `regionInfoMismatch` in the README.md
