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.
