-----------------------------------------
Summary: Remove noisy WARN from trying to construct MetricsServlet
Key: HBASE-28315
URL: https://issues.apache.org/jira/browse/HBASE-28315
Project: HBase
Issue Type: Improvement
Affects Versions: 3.0.0-beta-1, 2.6.0
Reporter: Bryan Beaudreault
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.
