> When mvn test in my environment, it reported the following.
> {noformat}
> 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]>
> {noformat}
> It's caused by the good resolving for the 'bad test' hostname 'a.b.c' as
> follows.
> {noformat}
> [drankye@zkdesk hadoop-common-project]$ ping a.b.c
> PING a.b.c (220.250.64.228) 56(84) bytes of data.
> {noformat}
> 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.
