Jorge Machado created SPARK-15505:
-------------------------------------
Summary: Explode nested Array in DF Column into Multiple Columns
Key: SPARK-15505
URL: https://issues.apache.org/jira/browse/SPARK-15505
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.6.1
Reporter: Jorge Machado
Priority: Minor
At the moment if we have a DF like this :
+------+---------+
| Col1 | Col2 |
+------+---------+
| 1 |[2, 3, 4]|
| 1 |[2, 3, 4]|
+------+---------+
There is no way to directly transform it into :
+------+------+------+------+
| Col1 | Col2 | Col3 | Col4 |
+------+------+------+------+
| 1 | 2 | 3 | 4 |
| 1 | 2 | 3 | 4 |
+------+------+------+------+
I think this should be easy to implement
