【错误】The node /hbase is not in ZooKeeper，Hbase端口占用无法正常启动

本人在启动zookeeper后，又启动HDFS，最后启动Hbase的时候，发现JPS进程中不显示HMaster进程，如下：

[hadoop@hadoop000 bin]$ jps3936 NameNode4241 SecondaryNameNode6561 Jps4041 DataNode3418 QuorumPeerMain

然后./hbase shell，发现出现下面的错误：

这是我之前的hbase-site.xml配置文件：

另外，我的hbase-env.sh中export HBASE_MANAGES_ZK=true 设置已经更改成了false，java路径也设置对了，下面是zookeeper中的zoo.cfg：

# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial # synchronization phase can takeinitLimit=10# The number of ticks that can pass between # sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.# do not use /tmp for storage, /tmp here is just # example sakes.dataDir=/home/hadoop/app/tmp/zk# the port at which the clients will connectclientPort=2181## Be sure to read the maintenance section of the # administrator guide before turning on autopurge.## http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance## The number of snapshots to retain in dataDir#autopurge.snapRetainCount=3# Purge task interval in hours# Set to "0" to disable auto purge feature#autopurge.purgeInterval=1

 查找不到原因，然后查看hbase/log中的log文件，发现了这条错误信息：

由于之前启动的zookeeper已经占用了2181端口，我不敢kill掉这个进程，但看提示是hbase需要在这个端口启动，我开始以为是hbase开启了自带的zookeeper与我外置打开的zookeeper冲突，在网上也找了很多方法，改了各种hbase-site.xml配置文件，但是还是不行， ZK was started at port: 2182，跟据这提示，我最后把hbase-site.xml中的2181端口改成了2182，成功启动了HMaster进程。./hbase shell命令也能正常使用。运行结果如下：
