I was recently trying to upgrade Hadoop from CDH4 to CDH5 ,however after upgrade found below issue , Looks like this is a known issue but unable to find a proper solution for it .

Code:
log4j:ERROR Could not find value for key log4j.appender.EventCounter log4j:ERROR Could not instantiate appender named "EventCounter".

I believe appender for EventCounter need to define again it's look like it's didn't got initialing properly.once you made changes do rolling restart of your cluster.
