HDFS文件内容追加报错的解决方法 原

报错内容：

Failed to replace a bad datanode on the existing pipeline due to no more good datanodes being available to try. (Nodes: current=[127.0.0.1:50010], original=[127.0.0.1:50010]). 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.

hdfs-site.xml中添加如下配置：

<property>
    <name>dfs.client.block.write.replace-datanode-on-failure.policy</name>
    <value>NEVER</value>
</property>
