Error Message
Failed to replace a bad datanode on the existing pipeline due to no more good datanodes being available to try. (Nodes: current=[DatanodeInfoWithStorage[127.0.0.1:46950,DS-e653e0ec-e490-47d3-9cca-cdd6dff3964a,DISK], DatanodeInfoWithStorage[127.0.0.1:34486,DS-fd83f642-be1a-44ed-8ba5-6ad5a42e85fd,DISK]], original=[DatanodeInfoWithStorage[127.0.0.1:34486,DS-fd83f642-be1a-44ed-8ba5-6ad5a42e85fd,DISK], DatanodeInfoWithStorage[127.0.0.1:46950,DS-e653e0ec-e490-47d3-9cca-cdd6dff3964a,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.
