Time elapsed: 11.422 sec <<< ERROR!
java.io.IOException: Failed to replace a bad datanode on the existing pipeline
due to no more good datanodes being available to try. (Nodes:
current=[DatanodeInfoWithStorage[127.0.0.1:63722,DS-9befc828-8ff7-4284-8fba-a6c55627ab3d,DISK]],

The current failed datanode replacement policy is ALWAYS, and a client may
configure this via 'dfs.client.block.write.replace-datanode-on-failure.policy'
in its configuration.
