Description

There are a couple of issues with replicating & remote reads of large encrypted blocks, which try to create buffers where they shouldn't. Some of this is properly limiting the size of arrays under SPARK-25904, but there are others specific to encryption & trying to convert EncryptedBlockData into a regular ByteBuffer.

EDIT: moved general array size stuff under SPARK-25904.
