【Hadoop】Hbase分布式链接出错的问题，启动后不能连上其他节点处理问题。一直报错The node /hbase is not in ZooKeeper.不能同步的问题。

以下是执行报错信息

很明显说明2181端口被占用了，又由于查了半天不知道这个端口是被哪个占用的，

我个人猜想是不是hadoop中间件系列哪个里面开了这个自带的zookeeper把这个默认的端口给占用了。

又不能确定，所以也不好kill掉这个端口，因此只能修改默认端口：

hbase-site.xml中修改

让2181变成2182

<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2182</value>
</property>

执行后结果

信息显示

可以看到成功。

同时我们打开web shell，看看之前输入list时候 提示的链接不上端口2181是否还存在。

hbase(main):001:0> list
TABLE
0 row(s) in 0.7930 seconds

=> []
hbase(main):002:0>

顺利执行

另外，在整个过程中，对配置的疑惑也顺便写下来。

第一，

即使是一个master 三个slave

但配置中quorum只能写其他三个slave

<property>
<name>base.zookeeper.quorum</name>
<value>slave1,slave2,slave3</value>
</property>

第二，为了保险起见，还是自己配置zookeeper吧……自带的都是坑(泪

那么你还需要修改环境hbase-env.sh。

export HBASE_MANAGES_ZK=false

第三，如果有报错说查看是否zookeeper.znode.parent配置好，

你直接在xml中定义会更好，免得出其他差错。

同时要配合rootserver一起来。

<property>
<name>zookeeper.znode.parent</name>
<value>/hbase</value>
<description>Root ZNode for HBase in ZooKeeper. All of HBase's ZooKeeper
files that are configured with a relative path will go under this node.
By default, all of HBase's ZooKeeper file path are configured with a
relative path, so they will all go under this directory unless changed.
</description>
</property>
<property>
<name>zookeeper.znode.rootserver</name>
<value>root-region-server</value>
<description>Path to ZNode holding root region location. This is written by
the master and read by clients and region servers. If a relative path is
given, the parent folder will be ${zookeeper.znode.parent}. By default,
this means the root location is stored at /hbase/root-region-server.
</description>
</property>

第四，你要不是伪分布式，请一定要指定

<property>
<name>hbase.cluser.distributed</name>
<value>true</value>
</property>
