背景
CDH集群切换数据盘，导致服务无法启动，卸载重装了 hbase、hdfs、yarn、oozie、spark等服务，未卸载重装的zookeeper、kafka。
重装hbase后无法创建表。
报错
hbase(main):001:0> create 'test','cf1'

问题排查与解决方案
排查：新装hbase HMaster / RS与原始卸载的HBase不在之前对应的节点上，zookeeper中信息未更新。
解决：进入zk客户端，删除/hbase ，并重启 hbase 服务
bash
# apache zookeeper访问路径： $ZOOKEEPER_HOME/bin/zkCli.sh
# CDH集群 zookeeper访问路径
sh /opt/cloudera/parcels/CDH/bin/zookeeper-client
# zk客户端下输入 ls /
[zk: localhost:2181(CONNECTED) 0] ls /
# 显示结果 [cluster, controller, brokers, zookeeper, yarn-leader-election, hadoop-ha, admin, isr_change_notification, log_dir_event_notification, controller_epoch, rmstore, consumers, hive_zookeeper_namespace_hive, latest_producer_id_block, config, hbase]
# zk 客户端下继续输入 rmr /hbase
[zk: localhost:2181(CONNECTED) 0] rmr /hbase
重点：一定要重启，不重启建表报错展示：
