Andrew Or resolved SPARK-12165. ------------------------------- Resolution: Fixed Fix Version/s: 1.6.0 > Execution memory requests may fail to evict storage blocks if storage memory > usage is below max memory > ------------------------------------------------------------------------------------------------------ > > Key: SPARK-12165 > URL: https://issues.apache.org/jira/browse/SPARK-12165 > Project: Spark > Issue Type: Bug > Components: Spark Core > Reporter: Josh Rosen > Assignee: Josh Rosen > Priority: Blocker > Fix For: 1.6.0 > > > Consider a scenario where storage memory usage has grown past the size of the > unevictable storage region ({{spark.memory.storageFraction}} * maxMemory) and > a task needs to acquire more execution memory by reclaiming evictable storage > memory. If the storage memory usage is less than maxMemory, then there's a > possibility that no storage blocks will be evicted. This is caused by how > {{MemoryStore.ensureFreeSpace()}} is called inside of > {{StorageMemoryPool.shrinkPoolToReclaimSpace()}}. > Here's a failing regression test which demonstrates this bug: > https://github.com/apache/spark/commit/b519fe628a9a2b8238dfedbfd9b74bdd2ddc0de4?diff=unified#diff-b3a7cd2e011e048908d70f743c0ed7cfR155 -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
