Hadoop Mismatched address stored in ZK for NameNode

背景

NN切换active状态报错导致无法切换，报错如下

hdfs haadmin -failover nn1 nn2

Operation failed:Mismatched address stored in ZK for NameNode at xx/xx:8020:Storedprotobuf was nameserviceId: "bigbigworld"
namenodeId:"nn1"
hostname: "xx"
port:  8041
zkfcPort:8019
,address from our own configuration for this NameNode was xx/xx:8020

# 8020 rpc端口
# 8041 servicerpc端口

处理过程

查看ZK存储数据

ls xxx

get xxx

格式化ZKFC

#2台 zkfc都停止，需要注意启停顺序，停止是先snn再ann，启动是先ann再snn
#先snn 再ann 停止
hdfs --daemon stop zkfc

#任意节点执行一次
hdfs zkfc -formatZK

# 此时查看zk查看hadoop-ha已删除

#先ann 再snn 启动
hdfs --daemon start zkfc
