Lokesh Jain commented on HDFS-12280:
------------------------------------
Hi
The error occurs if Datanode is running on the node on which we are running the
test. The port number 50011 is already in use in such a case. For the datanode
in MiniOzoneCluster to use different port either property "dfs.container.ipc"
needs to be set or property "dfs.container.ipc.random.port" needs to be set to
True.
