Subject [jira] [Created] (HBASE-12396) Document suggested use of log levels in dev guide
Date Fri, 31 Oct 2014 16:25:34 GMT
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.
