      Description

      Currently MR's IPC logging is very verbose. For example, I see a lot of:

      11/10/25 12:14:06 INFO ipc.YarnRPC: Creating YarnRPC for org.apache.hadoop.yarn.ipc.HadoopYarnProtoRPC
      11/10/25 12:14:06 INFO mapred.ResourceMgrDelegate: Connecting to ResourceManager at c0309.hal.cloudera.com/172.29.81.91:40012

      ... when submitting a job. This should be DEBUG level.
