齐柏林飞艇上未解决的关系

Question

当我在齐柏林飞艇上运行查询时，它将为所有表返回此错误。当我在蜂巢上运行相同的查询时，没有问题。蜂巢返回结果。 我使用火花解释器。 此代码也返回相同的错误

<table style="width:100%">
    <col width="100">
    <col>
    <col width="100">
    <tr class="red">
      <td height='100'> </td> <td>
      </td><td></td>
    </tr>
    <tr>
      <td colspan='3'> </td>
    </tr>
    <tr class="green">
      <td height='200'> </td>
      <td></td>
      <td> </td>
    </tr>
  </table>

但是当我尝试通过spark-shell运行它时，它会起作用。

我使用spark 2.1.0，齐柏林飞艇0.7.3

我想问，我可能会错过什么配置
