什么时候实现了自动 Spark RDD 分区缓存驱逐？

Question

In the past Spark would OOM a lot Spark java.lang.OutOfMemoryError: Java heap space

I've noticed since more recent (for me recent is 1.6+ since I started with 0.7) versions of Spark don't throw OOM if the RDD cannot fit in memory. Instead RDD partitions are evicted, and so they need to be recomputed.

I would like to know what version of Spark made this change?

I've tried reading through a lot of https://spark.apache.org/releases/ but cannot find anything definitive.

I'm pretty sure it was around 2.0, but can't find anything to prove it.

This Jira seems to imply that it was implemented along with unified memory management in 1.6 https://issues.apache.org/jira/browse/SPARK-14289

Answer 1

Borrowed storage memory may be evicted when memory pressure arises

From https://issues.apache.org/jira/secure/attachment/12765646/unified-memory-management-spark-10000.pdf , which is attached to https://issues.apache.org/jira/browse/SPARK-10000 which was implemented in 1.6 https://spark.apache.org/releases/spark-release-1-6-0.html

Found it in the end
