> [hbase] Keeping MapFile.Reader open is expensive: Part 2

> In hbase, a mapfile.Reader can be opened and a long period of time may pass
> before any accesses are made against the file. It can also be the case that
> a MapFile will be opened and never accessed. For every open unaccessed
> MapFile -- i.e. next or a record at some offset hasn't been pulled -- we'll
> consume two sockets in datanode, etc.
