>    Affects Versions: Impala 2.0

> tcmalloc spews for allocations of sufficient size. It looks like:
> tcmalloc: large alloc 1073741824 bytes == nil @ 0x13f3c56 0x720156
> tcmalloc: large alloc 1275068416 bytes == nil @ 0x13f3c56 0x720156
> We should increase this value. These allocations are ~1GB which is fine and the spew
is potentially confusing.
