Reduce log level on MR2 IPC construction, etc
---------------------------------------------
Key: MAPREDUCE-3265
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3265
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: mrv2
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Priority: Minor
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
11/10/25 12:14:06 INFO ipc.HadoopYarnRPC: Creating a HadoopYarnProtoRpc proxy
for protocol interface org.apache.hadoop.yarn.api.ClientRMProtocol
11/10/25 12:14:07 INFO mapred.ResourceMgrDelegate: Connected to ResourceManager
at c0309.hal.cloudera.com/172.29.81.91:40012
11/10/25 12:14:08 INFO mapred.ClientCache: Connecting to HistoryServer at:
c0309.hal.cloudera.com:10020
11/10/25 12:14:08 INFO ipc.YarnRPC: Creating YarnRPC for
org.apache.hadoop.yarn.ipc.HadoopYarnProtoRPC
11/10/25 12:14:08 INFO mapred.ClientCache: Connected to HistoryServer at:
c0309.hal.cloudera.com:10020
11/10/25 12:14:08 INFO ipc.HadoopYarnRPC: Creating a HadoopYarnProtoRpc proxy
for protocol interface org.apache.hadoop.mapreduce.v2.api.MRClientProtocol
... when submitting a job. This should be DEBUG level.
