      Description

      when run only a UT of TestBlockManager#testOneOfTwoRacksDecommissioned(), it will fail and throw NullPointerException.
      Since NameNode#metrics is static variableļ¼Œrun all uts in TestBlockManager and other ut has init metrics.
      But that it runs only testOneOfTwoRacksDecommissioned without initialing metrics throws NullPointerException.

      java.lang.NullPointerException
