Wei Zhou updated HDFS-11186:
----------------------------
    Comment: was deleted

(was: Hi [~rakeshr], thanks for reviewing the patch! The reason is that it 
takes extra time to stop NN than previous.
{code}
    try {
      storagePolicySatisfierThread.join(3000);
    } catch (InterruptedException ie) {
    }
{code}
It will take longer time to finish for tests that have to change NN HA states 
or restart NN, and this leads to timeout failure.)
