启动zookeeper后看到2181端口已经占用
然后运行：zkCli.sh -server server1:2181
运行后在welcome to zookeeper!后不断出错误信息：
- Opening socket connection to server localhost/0:0:0:0:0:0:0:1:2181. Will not attempt to authenticate using SASL (unknown error)
JLine support is enabled

其中的dataDir目录和dataLogDir都已经建立好。也已经在三台服务器的dataDir目录里建立myid的对应文件
hosts文件：PXA270的视频监控系统设计与开发+帧对比算法

奇怪的是，我的hbase使用的这三个zookeeper，在hbase shell里看状态说三台hbase服务器都正常启动了，难道这个错误无关紧要？
hbase-site.xml的内容是：
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://hadoop98:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.master</name>
<value>hdfs://hadoop98:6000</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>hadoop98,hadoop30,hadoop40</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
hbase-env.sh中的 HBASE_MANAGES_ZK也设置为false
这样，myid从0开始配置
如果不行，关闭2个ZK，只留一个
再不行，用HBASE托管拉起试试
