在master服务器端/usr/local/hbase/bin目录下执行：[root@master bin]# hbase zkcli ;

错误信息：

解决方案：

检查hadoop的配置文件：

[root@master ~]# cd /usr/local/hadoop/etc/hadoop/
[root@master hadoop]# ls
capacity-scheduler.xml      hadoop-policy.xml        kms-log4j.properties        slaves
configuration.xsl           hdfs-site.xml            kms-site.xml                ssl-client.xml.example
container-executor.cfg      httpfs-env.sh            log4j.properties            ssl-server.xml.example
core-site.xml               httpfs-log4j.properties  mapred-env.cmd              yarn-env.cmd
hadoop-env.cmd              httpfs-signature.secret  mapred-env.sh               yarn-env.sh
hadoop-env.sh               httpfs-site.xml          mapred-queues.xml.template  yarn-site.xml
hadoop-metrics2.properties  kms-acls.xml             mapred-site.xml
hadoop-metrics.properties   kms-env.sh               mapred-site.xml.template

vi core-site.xml

<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://master:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/var/hadoop</value>
</property>
</configuration>

检查Hbase配置文件：

<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master:9000</value>
</property>

<property>
<name>hbase.master</name>
<value>master</value>
</property>

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

<property>
<name>hbase.ZooKeeper.property.clientPort</name>
<value>2181</value>
</property>

<property>
<name>hbase.ZooKeeper.quorum</name>
<value>slave1,slave2,slave3</value>
</property>
解决方法：fs.defaultFS的Value值与hbase.rootdir的Value值保持一致;
