> 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[127.0.0.1:52139,DS-1db5fb50-ea3a-4ae2-8b37-ebda1a947c34,DISK],
DatanodeInfoWithStorage[127.0.0.1:49736,DS-2929c4a8-389a-4ff3-92be-1539018d17d9,DISK]], original=[DatanodeInfoWithStorage[127.0.0.1:52139,DS-1db5fb50-ea3a-4ae2-8b37-ebda1a947c34,DISK],
DatanodeInfoWithStorage[127.0.0.1:49736,DS-2929c4a8-389a-4ff3-92be-1539018d17d9,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.
