------------------------------------
Summary: Replicating a block > 2gb with encryption fails
Key: SPARK-25827
URL: https://issues.apache.org/jira/browse/SPARK-25827
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.4.0
Reporter: Imran Rashid
When replicating large blocks with encryption, we try to allocate an array of
size {{Int.MaxValue}} which is just a bit too big for the JVM. This is
basically the same as SPARK-25704, just another case.
In DiskStore:
{code}
val chunkSize = math.min(remaining, Int.MaxValue)
{code}
{noformat}
