      Bug #53736  	ndbd stdout log should track arbitrator
      
      When in arbit prep phase (just before start) the president node now says:
      
      2010-05-18 10:15:34 [ndbd] INFO     -- Setting arbitrator to node 1
      
      And the other data nodes say:
      
      2010-05-18 10:15:34 [ndbd] INFO     -- President node 3 sets arbitrator to node 1

Fixed in NDB 7.0+. Documented in the NDB 7.0.36, 7.1.25, 7.2.9, and 7.3.1 changelogs as follows:

        Data node logs now provide tracking information about 
        arbitrations, including which nodes assumed the arbitrator role 
        and at what times.

Closed.
