可视化界面读取不到数据

Question

我上个问题是问的PK哥提供的imooc-spark-web运行问题，我接着用自己的跟着视频制作的pk-spark-web运行测试，我将其打包传入linux运行，可视化界面依然读取不到数据，我的HBase上是存储的有数据的，不知道我是少了什么步骤吗，查看nohup.out

我觉得pk哥既然能实现可视化，教的内容自然是没有问题的，可视化的方法有很多，我们这个课程也主要是讲数据实时处理的，可视化显示问题我自己通过别的方式解决吧

• Michael_PK #1

  你把浏览器的开发者工具打开，看看请求有返回值吗？ 或者是有什么错误信息

• Michael_PK #2

  开发者工具上应该能看到是否有请求过去以及是否有数据返回

• 提问者 大数据的童鞋 回复 Michael_PK #3

  我在本地idea能够查询HBase数据，那我就足够实现可视化操作了，有一点疑问是，我在本地就能够完成，为什么要放在linux系统上实现，哦，我这样处理是处理的离线数据相当于，您教的是实时展示数据吧
