> The description in 
> [SPARK-21860|https://issues.apache.org/jira/browse/SPARK-21860]:
> In `HeapMemoryAllocator`, when allocating memory from pool, and the key of 
> pool is memory size.
> Actually some size of memory ,such as 1025bytes,1026bytes,......1032bytes, we 
> can think they are the same，because we allocate memory in multiples of 8 
> bytes.
> In this case, we can improve memory reuse.
