      Description

      When mvn test in my environment, it reported the following.

      Failed tests: 
        TestTableMapping.testClearingCachedMappings:144 expected:</[rack1]> but was:</[default-rack]>
        TestTableMapping.testTableCaching:79 expected:</[rack1]> but was:</[default-rack]>
        TestTableMapping.testResolve:56 expected:</[rack1]> but was:</[default-rack]>
      

      It's caused by the good resolving for the 'bad test' hostname 'a.b.c' as follows.

      [drankye@zkdesk hadoop-common-project]$ ping a.b.c
      PING a.b.c (220.250.64.228) 56(84) bytes of data.
      

      I understand it may happen in just my local environment, and document this just in case others also meet this. We may use even worse hostname than 'a.b.c' to avoid such situation.
