> Umbrella issue on memory management. One-stop shop to learn how we're doing
> it, tenets, and work to be done. Collect it all in one place so we are
> aligned rather than each trying to do it for themselves.
> Subtasks include:
> + Map of memory allocation and recycling landscape
> + Where are we allocating when we could be recycling
> + MSLAB and G1GC don't go together?
> + Enable MSLAB pool always?
> + With offheap allocations, less GC but it runs for longer?
> + Better heuristics recycling: e.g. HBASE-15525 OutOfMemory could occur when
> using BoundedByteBufferPool during RPC bursts
> + See if can do DFSClient buffer reuse: HBASE-15506
> FSDataOutputStream.write() allocates new byte buffer on each operation
> What else?
