Namenode 开启HA之后,由于zookeeper异常,出现脑裂现象

执行

$./hdfs haadmin -getServiceState nn1                                                                                                                                                 

standby                                                               

$./hdfs haadmin -getServiceState nn2

standby   

两个互为HA的namenode节点均处于standby 状态,随后执行

$/hdfs haadmin -transitionToActive --forcemanual nn1

强行手工将namenode1状态转换为active

PS: serverID即namenodeID,可以访问http://namenodeip:50070界面查看
