Description

I occasionally see this WARN message out of the NameNode:

12/07/19 10:37:37 WARN ipc.Server: Ignoring socket shutdown exception

with no further details. This message isn't useful - it either needs to have more contextual information (eg what client it's talking about and the exception ignored), or should be reduced to debug level.
