Wei-Chiu Chuang commented on HBASE-20577:
-----------------------------------------
The original LogLevel looked like its 1990s because it was cloned from Hadoop's
LogLevel implementation, and it was intented to be used as acommand line tool
(e.g. hadoop daemonlog), so there wasn't much fancy UI.
I still find it useful to use hadoop's daemonlog command line tool to change
log level dynamically (and you can still use hadoop's daemonlog command against
HBase (hint: hbase org.apache.hadoop.log.LogLevel). Partly because getting a
browser to enable SPNEGO & kinit is painful, if you run it on a secure cluster.
Would the new patch serve the old purpose (i.e.g changing log level from
command line)? Or do HBase community think the use of command line loglevel is
diminished and everyone uses the web UI instead?
Thanks!

> The Log Level page in web UI seems out of the place. I think we should make
> it look consistent with design of other pages in HBase web UI.
> Also, validation of required fields should be done, otherwise user should not
> be allowed to click submit button.
