--------------------------------
Summary: 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: 2.2.1
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.
