hdfs failover controller无法启动,报错:

error zkfailoverController

Unable to start failover controller. Parent zoned does not exist.

Run with -formatZK flag to initialize ZooKeeper.

解决方案:1、cd /opt/cloudera/parcels/CDH/lib/zookeeper/bin/

./zkCli.sh

ls / 查看没有hadoop ha

2、停止hdfs服务,在namenode节点上执行hdfs zkfc -formatZK

3、在两个namenode节点上启动zkfc服务

cd /opt/clodudera/parcels/CDH-6.1.1-1/lib/hadoop/sbin

./hadoop-daemon.sh start zkfc
