> 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[127.0.0.1:47227,DS-dd109c14-79e5-4380-ac5e-4434cd7e25b5,DISK],

DatanodeInfoWithStorage[127.0.0.1:56949,DS-6c0be75e-a78c-41b9-bfd0-7ee0cdefaa0e,DISK]]). The
current failed datanode replacement policy is DEFAULT, and a client may configure this via
'dfs.client.block.write.replace-datanode-on-failure.policy' in its configuration.
