    Root Cause Analysis

    1. 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[10.6.25.184:50010,DS-a67e1753-7160-4c87-8a87-330732f6ac30,DISK], DatanodeInfoWithStorage[10.6.25.189:50010,DS-f42cdbb3-7981-4630-8b98-0ac04bdf92a2,DISK]], original=[DatanodeInfoWithStorage[10.6.25.184:50010,DS-a67e1753-7160-4c87-8a87-330732f6ac30,DISK], DatanodeInfoWithStorage[10.6.25.189:50010,DS-f42cdbb3-7981-4630-8b98-0ac04bdf92a2,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.
