> Fix the ARRAY_MAX in BufferHolder and add a test
> ------------------------------------------------
>
> Key: SPARK-22222
> URL: https://issues.apache.org/jira/browse/SPARK-22222
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Feng Liu
>
> This is actually a followup for SPARK-22033, which set the `ARRAY_MAX` to `Int.MaxValue
- 8`. It is not a valid number because it will cause the following line fail when such a large
byte array is allocated: https://github.com/apache/spark/blob/master/sql/catalyst/src/main/java/org/apache/spark/sql/catalyst/expressions/codegen/BufferHolder.java#L86
We need to make sure the new length is a multiple of 8.
> We need to add one test for the fix. Note that the test should work independently with
the heap size of the test JVM.
