本文总结了HBase在运行时遇到的连接ZooKeeper错误，包括'KeeperErrorCode = ConnectionLoss for /hbase'的问题。解决方法是检查HBASE_MANAGES_ZK属性设置，确保其为false，并安装及正确配置Zookeeper。同时强调启动HBase前需确保HDFS和Zookeeper已启动，遵循HDFS -> Zookeeper -> HBase的启动顺序。

2017-04-07 02:32:01,081 ERROR [main] client.ConnectionManager$HConnectionImplementation: Can't get connection to ZooKeeper: KeeperErrorCode = ConnectionLoss for /hbase

ERROR: KeeperErrorCode = ConnectionLoss for /hbase

Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:

hbase> list
hbase> list 'abc.*'
hbase> list 'ns:abc.*'
hbase> list 'ns:.*'

hbase(main):004:0>

出现错误：

2015-05-25 20:26:14,949 ERROR [main] client.ConnectionManager$HConnectionImplementation: Can’t get connection to ZooKeeper: KeeperErrorCode = ConnectionLoss for /hbase
设置 conf/hbase-env.sh文件中的HBASE_MANAGES_ZK 属性为 false

错误原因是没有安装zookeeper，需要配置

2、运行HBase
启动hbase时要确保hdfs已经启动，HBase的启动顺序为：HDFS->Zookeeper->HBase，运行命令如下:

<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>master,slave1</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/hadoop/opt/zookeeper-3.4.6</value>
</property>
</configuration>
