Hbase启动失败 zookeeper MetaTableLocator Failed verification of

用 Hadoop namenode -fromat 格式化后，用./start-Hbase.sh 启动HMaster和HRegionServer，但是过几秒种后HMaster进程自动关闭，HRegionServer进程没有关闭，查看日志报如下错：

Hbase启动失败 zookeeper MetaTableLocator Failed verification of

我网上查了很多资料，都没有找到答案。最后想到这是因为我格式化了HDFS后产生的问题，原来是好的。是不是因为zookeeper中某些文件遗留的原因导致的呢？所以我将dataDir=/opt/zookeeper-3.4.5/data 目录下的version-2给删除，并且重启了服务器。然后重启开启后，HMaster进程正常运行。再打开 dataDir=/opt/zookeeper-3.4.5/data目录发现产生了新的version-2  ，并且多了 zookeeper_server.pid这个文件。我不知道当时是否是因为缺少zookeeper_server.pid这个文件导致的原因呢。

所以发现格式化HDFS还是可能会产生很多意想不到的问题的。所以今天产生的这些问题告诉我，重新格式化之前，最好先关闭相关进程，并且删除hadoop下的tmp目录(master和slave都要删),并且zookeeper下的dataDir下的文件也要注意，然后严格按照下面步骤格式化：

 ###注意：严格按照下面的步骤
  1.启动zookeeper集群（分别在itcast05、itcast06、tcast07上启动zk）
   cd /itcast/zookeeper-3.4.5/bin/
   ./zkServer.sh start
   #查看状态：一个leader，两个follower
   ./zkServer.sh status
  2.启动journalnode（分别在在itcast05、itcast06、tcast07上执行）
   cd /itcast/hadoop-2.4.1
   sbin/hadoop-daemon.sh start journalnode
   #运行jps命令检验，itcast05、itcast06、itcast07上多了JournalNode进程
  3.格式化HDFS
   #在itcast01上执行命令:
   hdfs namenode -format
   #格式化后会在根据core-site.xml中的hadoop.tmp.dir配置生成个文件，这里我配置的是/itcast/hadoop-2.4.1/tmp，然后将/itcast/hadoop-2.4.1/tmp拷贝到itcast02的/itcast/hadoop-2.4.1/下。
   scp -r tmp/ itcast02:/itcast/hadoop-2.4.1/（如果tmp没有东西，此步可以跳过）
  4.如果zookeeper设置了高可用HA，否则跳过该步，格式化ZK(在itcast01上执行即可)
   hdfs zkfc -formatZK
  5.启动HDFS(在itcast01上执行)
   sbin/start-dfs.sh

  6.启动YARN(#####注意#####：是在itcast03上执行start-yarn.sh，把namenode和resourcemanager分开是因为性能问题，因为他们都要占用大量资源，所以把他们分开了，他们分开了就要分别在不同的机器上启动)
   sbin/start-yarn.sh

7.启动Hbase

   hbase/bin/start-hbase.sh
