問題描述
在使用hdfs api追加內(nèi)容操作，從windows電腦上的idea對(duì)aliyun服務(wù)器上的hdfs中的文件追加內(nèi)容時(shí)，出現(xiàn)錯(cuò)誤，如下：

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[172.25.55.228:9866,DS-6ba619cf-5189-45c7-8dbc-56afa381ab0b,DISK]], original=[DatanodeInfoWithStorage[172.25.55.228:9866,DS-6ba619cf-5189-45c7-8dbc-56afa381ab0b,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.

問題解決
在idea代碼中添加
