kondziolka9ld updated SPARK-45249:
----------------------------------
Description:
Hi!
I consider why `isCheckpointed` method return `false` - could someone explain
it? I would expect `true`.
{code:java}
Welcome to
____ __
/ __/__ ___ _____/ /__
_\ \/ _ \/ _ `/ __/ '_/
/___/ .__/\_,_/_/ /_/\_\ version 3.3.0
/_/
Using Scala version 2.12.15 (OpenJDK 64-Bit Server VM, Java 11.0.13)
Type in expressions to have them evaluated.
Type :help for more information.
