Xiaoyu Yao commented on HDFS-12324:
-----------------------------------
New stack after HDFS-12216, where {{MiniOzoneCluster#restartDataNode}} will
call {{MiniDFSCluster#waitActive()}} and eventually timeout. Before HDFS-12216,
the test passed because we don't check wait for cluster active for
restartDataNode.
Since the each individual test in TestQueryNode will create its own Mini
cluster, I think we can fix the test by removing the two restartDatanode calls.
