Sean Busbey created HBASE-20438:
-----------------------------------

             Summary: Add an HBase antipattern check for reintroducing 
commons-logging
                 Key: HBASE-20438
                 URL: https://issues.apache.org/jira/browse/HBASE-20438
             Project: HBase
          Issue Type: Improvement
          Components: dependencies, test
    Affects Versions: 3.0.0, 2.1.0, 2.0.0
            Reporter: Sean Busbey
             Fix For: 3.0.0, 2.1.0, 2.0.1


We moved to slf4j in HBASE-10092, but looking at our source tree we've had some 
regression back to commons-logging:

We should do the same kind of check that we do to avoid e.g. the Hadoop 
annotations
