虽然 docker很方便，但是在连接HBase时需要打通网络，由于本地HBase是localhost，访问有问题，所以放弃 docker 版sdc，改为本地解压版。

SDC本地解压版：

sdc支持的HBase版本下文测试环境演示实例中可以看到。

Phoenix与HBase服务的集成：

只需要将 Phoenix包解压后的phoenix-5.0.0-HBase-2.0-server.jar 和 phoenix-core-5.0.0-HBase-2.0.jar两个jar包拷贝到hbase的lib目录下，修改hbase-site.xml，添加相关配置，重启hbase集群即可。

  <property>
    <name>phoenix.schema.isNamespaceMappingEnabled</name>
    <value>true</value>
  </property>
  <property>
    <name>phoenix.schema.mapSystemTablesToNamespace</name>
    <value>true</value>
  </property>

为了方便通过sqlline.py 访问 phoenix，将hbase-site.xml复制一份到phoenix的bin目录下。

简单演示一下，往 MySQL test.user表中插入和更新数据

INSERT INTO `test`.`user`(`id`, `user_name`, `update_time`) VALUES (2, 'ZLXX_INSERT', SYSDATE());

StreamSets实时采集MySQL数据到HBase

Record Count (since last startup)上面显示数量大于1是因为查询 SQL 里面的更新时间是大于等于OFFSET，而且每10秒扫描一次，因此会不断被扫描到，SQL里面加上了最近五分钟的限制，因此重复次数不会太多，如果是大于OFFSET，有可能会导致数据丢失。

需要注意上面 Phoenix映射表的时候，两个ID字段，命名需要注意。
