> Priority: Minor
> Attachments: HBASE-21921.HBASE-21879.v01.patch,

>
> As the javadoc of ByteBuffAllocator says:
> {code}
> There's possible that the desired memory size is large than ByteBufferPool
> has, we'll downgrade to allocate ByteBuffers from heap which meaning the GC
> pressure may increase again. Of course, an better way is increasing the
> ByteBufferPool size if we detected this case.
> {code}
> So I think we need some messages to remind the user that an larger
> ByteBufferPool size may be better if the allocator allocate ByteBuffer from
> heap frequently.
