这篇文章主要介绍了spark怎么读取hbase表的相关知识，内容详细易懂，操作简单快捷，具有一定借鉴价值，相信大家阅读完这篇spark怎么读取hbase表文章都会有所收获，下面我们一起来看看吧。

一.场景:
    spark通过phoenix 读取hbase表，其实说白了先要去Zookeeper建立connection。

二.代码:

1. val zkUrl = "192.168.100.39,192.168.100.40,192.168.100.41:2181"
   

2. val formatStr = "org.apache.phoenix.spark"
   

3. val oms_orderinfoDF = spark.read.format(formatStr)
   

4.   .options(Map("table" -> "oms_orderinfo", "zkUrl" -> zkUrl))
   

5.   .load

三.查看SparkJob日志:
