    Description

      Nodes in drain mode with slaveOk specified should be able to accept reads. Currently, you get a "node is recovering" error instead. The logic in Command::execCommand() needs to be tightened up when detecting nodes actually in RECOVERING state versus PRIMARY but can't do writes (otherwise known as 'drain mode').
