我想转换具有以下架构结构的Pyspark数据框。
root
|-- top: long (nullable = true)
|-- inner: struct (nullable = true)
| |-- inner1: long (nullable = true)
| |-- inner2: long (nullable = true)
| |-- inner3: date (nullable = true)
| |-- inner4: date (nullable = true)
收件人：
root
|-- top: long (nullable = true)
|-- inner: array (nullable = true)
| |-- element: struct (containsNull = true)
| | |-- inner1: long (nullable = true)
| | |-- inner2: long (nullable = true)
| | |-- inner3: date (nullable = true)
| | |-- inner4: date (nullable = true)
这基本上正在改变
top | [ inner1, inner2, inner3, inner4]
到
top | [[inner1, inner2, inner3, inner4]]
