new 5129cbe3a6a HBASE-27814 Add support for dump and process metrics
servlet in REST InfoServer (#5215)
5129cbe3a6a is described below
commit 5129cbe3a6aa90e8e5112b65d007893bcec126a8
Author: Nihal Jain <nihalj...@apache.org>
AuthorDate: Sun Jan 14 11:59:26 2024 +0530
HBASE-27814 Add support for dump and process metrics servlet in REST
InfoServer (#5215)
Other changes:
- Ensure info server stops during stop()
- Extract header and footer. This would fix the log level page layout for
rest web UI (See HBASE-20693)
- Add hostname in the landing page instead of just port similar to other
web UIs
Signed-off-by: Nick Dimiduk <ndimi...@apache.org>
(cherry picked from commit a683fcfbe8c5c84e58fa8670f4414f9d01ff43ed)
