Summary: Support type judgment for ArrayData
Key: SPARK-30110
URL: https://issues.apache.org/jira/browse/SPARK-30110
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.0
Reporter: jiaan.geng
Fix For: 3.0.0
ArrayData is only some interfaces for getting data, such as: getBoolean,
getByte.
When the element type of array is unknow, I want to judgment the element type
first.
I have PR working in process:
[https://github.com/beliefer/spark/commit/5787c6f062795aa7931c58ac2302ba607d3a97aa]
The array function ArrayNDims is used to get the Dimension of array.
If ArrayData can support some interfaces like isBoolean, isByte, isArray, My
job will be easier.
