Subject Re: About memory leak in spark 1.4.1
Date Sun, 02 Aug 2015 08:11:29 GMT
reducing did the trick for me. Heap doesn't
get filled because it is reserved..
My reasoning is:
I give executor all the memory i can give it, so that makes it a boundary.
>From here i try to make the best use of memory I can.
storage.memoryFraction is in a sense user data space.  The rest can be used
by the system.
If you don't have so much data that you MUST store in memory for
performance, better give spark more space..
ended up setting it to 0.3

All that said, it is on spark 1.3 on cluster

hope that helps
