log4j:ERROR Could not instantiate appender named "EventCounter".
The following steps will be run, in order:
  1: /home/benmayne/code/drake/demos/c4/././out.csv <- /home/benmayne/code/drake/demos/c4/././in.json [missing output]
  2: /home/benmayne/code/drake/demos/c4/././long-lastnames.json <- /home/benmayne/code/drake/demos/c4/././in.json [missing output]
Confirm? [y/n]

[BMayneFactual]

just kidding. looks like my problem

[pnee]

This is how I fixed it, in the /etc/hadoop/conf/log4j.properties
You need to change

log4j.appender.EventCounter=org.apache.hadoop.log.metrics.EventCounter

to
log4j.appender.EventCounter=org.apache.hadoop.log.metrics.jvm.EventCounter
