I saw this exception while running spark streaming on EMR 16/04/14 13:49:10 WARN memory.TaskMemoryManager: leak 32.3 MB memory from org.apache.spark.unsafe.map.BytesToBytesMap@34158d5f 16/04/14 13:49:10 ERROR executor.Executor: Managed memory leak detected; size = 33816576 bytes, TID = 2942915 16/04/14 13:49:10 ERROR executor.Executor: Exception in task 22.0 in stage 35684.0 (TID 2942915) java.lang.OutOfMemoryError: Unable to acquire 262144 bytes of memory, got 220032 –  Apr 20 '16 at 9:27 

Were you able to resolve it? I am facing a similar issue of memory leak in spark 1.6.2 –  Mar 24 at 18:43

I think in my case it was . It is fixed in Spark 2.0.0 and we are using 2.1.0 now, so all is good. –  Mar 25 at 20:10

does all these comment mean, if I can not upgrade to the 'good' version yet due to company IT readiness, I can safely ignore the error? I am currently using spark 1.6.0 and having errors like this when some dataframe does 'distinct' and then 'head'. –  Aug 8 at 9:55 

Well, if ignoring it is your only option, I suggest you ignore it :). It may lead to out-of-memory issues, being a warning about memory mis-accounting. –  Aug 8 at 10:31
