Chang Li commented on MAPREDUCE-6354:
-------------------------------------

[~jlowe] Thanks for review! Have updated my patch. Have tested the logging and 
the connection info is logged as following
{code}
shuffle for job_1430770193094_0002 reducer 0, 
maps=[attempt_1430770193094_0002_m_000000_0, 
attempt_1430770193094_0002_m_000001_0]
{code}

> shuffle handler should log connection info
