KeeperErrorCode = NoNode for /admin/preferred_replica_election

Zookeeper运行报错信息如下：

INFO Got user-level KeeperException when processing sessionid:0x156028651c00001 type:delete cxid:0x1b zxid:0x59 txntype:-1 reqpath:n/a Error Path:/admin/preferred_replica_election Error:KeeperErrorCode = NoNode for /admin/preferred_replica_election (org.apache.zookeeper.server.PrepRequestProcessor)

解决办法：

1 关闭Zookeeper。

2 删除自己设定的dataDir路径下的version-2文件夹。

3 重启Zookeeper。
