> Remove noisy WARN from trying to construct MetricsServlet
> ---------------------------------------------------------
>
> Key: HBASE-28315
> URL: https://issues.apache.org/jira/browse/HBASE-28315
> Project: HBase
> Issue Type: Bug
> Affects Versions: 3.0.0-beta-1
> Reporter: Bryan Beaudreault
> Assignee: Bryan Beaudreault
> Priority: Major
> Fix For: 2.6.0, 3.0.0-beta-2
>
>
> MetricsServlet is deprecated since hadoop 2.8 and removed in hadoop3. In
> HBASE-20904 the servlet initialization was refactored, and we now have a
> noisy WARN (with stacktrace) when MetricsServlet does not exist. This should
> be common, since hadoop3 is the modern version to run on (hadoop2 almost
> EOL). We shouldn't warn.
> Fix the code to not produce a warn when MetricsServlet is not available.
