> To read/write data from HDFS on data node, applications establise TCP/IP connections
with the datanode. The HDFS read can be controled by setting Linux Traffic Control  (TC) subsystem
on the data node to make filters on appropriate connections.
> The current cgroups net_cls concept can not be applied on the node where the container
is launched, netheir on data node since:
> -   TC hanldes outgoing bandwidth only, so it can be set on container node (HDFS read
= incoming data for the container)
> -   Since HDFS data node is handled by only one process,  it is not possible to use net_cls
to separate connections from different containers to the datanode.
> Tasks:
> 1) Extend Resource model to define bandwidth enforcement rate
> 2) Monitor TCP/IP connection estabilised by container handling process and its child
processes
> 3) Set Linux Traffic Control rules on data node base on address:port pairs in order to
enforce bandwidth of outgoing data
> Concept: http://www.hit.bme.hu/~do/papers/EnforcementDesign.pdf
> Implementation:
