> FSHLog module uses a map to reuse SyncFuture objects, and assumes that this
> map will be used by RPC Handler threads only. but, in some cases, this
> assumption is wrong.
> for example, if some coprocessors are registered, and these coprocessors uses
> CoprocessorHConnection insteadof HConnection, and request some puts/ or
> deletes throgh CoprocessorHConnection, all mutations will be handled by
> hconnection's batchPool, not RPC Handlers. because hconnection's batchPool is
> dynamically growing or shrinking, all new threads in hconnection are put to
> the map in FSHLog, and this map will grow continuously.
> in attached image file, the map to reuse SyncFuture occupies about 4GB memory
> and has (almost all) entries holding hconnection's thread.
