Hi Arun,
Before I file a jira, I want to make sure it's not a simple
misconfiguration on my part, or a "wrong" jar in the classpath,
or something else obvious to current developers.
I was running a streaming job, here's all I could find in the
tasktracker's log:
2011-07-14 07:24:20,307 WARN org.apache.hadoop.ipc.Server: IPC Server
