The warn log {{Get pipeline call failed. We are not able to find free nodes or operational
pipeline.}} is the failed reason. This is broken by the change in HDFS-12756. It didn't reset
datanode num and use default value.
{code}
-    cluster = new MiniOzoneCluster.Builder(conf).numDataNodes(5)
+    cluster = new MiniOzoneClassicCluster.Builder(conf)
{code}
