Tim Armstrong updated IMPALA-1034:
----------------------------------
Description: (was: Releasing the memory in the maintenance thread is
insufficient because
1) the default wake up time is 30sec, which is too long and
2) there's some overhead that we can't even free.
Although the mem tracker is already tracking all the mem usage by tcmalloc, we
still see cases where the RSS memory exceed mem-limit. This leads to excessive
swapping.
One potential fix is to move away from tcmalloc.)
> Verify RSS stays within mem_limit + JVM heapsize
