Sean Busbey created HBASE-12396:
-----------------------------------
Summary: Document suggested use of log levels in dev guide
Key: HBASE-12396
URL: https://issues.apache.org/jira/browse/HBASE-12396
Project: HBase
Issue Type: Improvement
Components: documentation
Reporter: Sean Busbey
Priority: Minor
Right now we don't provide any guidance on appropriate use of log levels, which
leads to inconsistent use and in some cases exacerbating problems for tests and
troubleshooting (see HBASE-12395). We should add a section on suggested use of
log levels to the guide.
