> DeadLock happens when ‘StaticMemoryManager‘ release in-memory block
> -------------------------------------------------------------------
>
> Key: SPARK-16564
> URL: https://issues.apache.org/jira/browse/SPARK-16564
> Project: Spark
> Issue Type: Bug
> Affects Versions: 1.6.1
> Environment: spark.memory.useLegacyMode=true
> Reporter: roncenzhao
>
> the condition causes dead lock is:
> Thread 1. 'BlockManagerSlaveEndpoint' receives 'RemoveBroadcast' or 'RemoveBlock' or .., executor begins to remove block named 'blockId1'
> Thread 2. the other rdd begins to run and must 'evictBlocksToFreeSpace()' for more memory, unfortunately the chosen block to evict is 'blockId1'
> As follows,
> thread 1 is holding blockId1's blockInfo lock(0x000000053ab39f58) and waitting for StaticMemoryManager's lock(0x000000039f04fea8).
> thread 2 is holding StaticMemoryManager's lock(0x000000039f04fea8) and waitting for blockId1's blockInfo lock(0x000000053ab39f58).
> This condition causes dead lock.
> stackTrace:
> Found one Java-level deadlock:
