Initialization failed for Block pool BP-XX (Datanode Uuid xxx) service to

配置hdfs namenode HA:

hdfs zkfc –formatZK  

 

Initialization failed for Block pool BP-666417012-10.253.76.213-1557044865448 (Datanode Uuid 5132035c-8d6a-4617-af7e-7d07355a905b) service to hzd-t-vbdl-02/10.253.76.222:8022 Blockpool ID mismatch: previously connected to Blockpool ID BP-666417012-10.253.76.213-1557044865448 but now connected to Blockpool ID BP-1262695848-10.253.76.222-1557045124181

 

出现该错误是因为配置namenode HA,执行了两次format namenode,

导致出险该错误 

将 最先执行format的内容拷贝到另外一个 namenode节点,具体路径看个人的配置,

比如:/XXX/hdfs/dfs/dn/current/VERSION
拷贝完成重启namenode以及DataNodes

ha 配置的节点如下
