HBase表设计
create ‘imooc_course_search_clickcount‘,‘info‘
rowkey设计：也是根据我们的业务需求来的

提交作业时，注意事项：
1）--packages的使用
2）--jars的使用

建表：create ‘imooc_course_search_clickcount‘,‘info‘
删除表的内容：truncate ‘imooc_course_search_clickcount‘
打包到服务器运行：
注意点1.打包 2.--packages 3.--jars
1、java与scala混合打包，所以要去掉pom.xml里的<build>下的SourceDirectory与testSourceDirectory
否则：mvn clean package -DskipTests 会报错，也可以maven project栏右键打包
2、--packages org.apache.spark:spark-streaming-kafka-0-8_2.11:2.2.1
格式：分别是pom.xml里面的groupId、Arcticid、spark-version（用分号分开）
3、--jars（一个一个导包太繁琐，所以可以采用这种方式）
--jars $(echo /home/hadoop/app/hbase-1.2.0-cdh5.7.0/lib/*.jar | tr ‘ ‘ ‘,‘)
如有多个hbase.submit进程，可以杀掉
