Hello (Again):
I've managed to get Map/Reduce on its feet and running, but the JobClient
runs the Map() to 100% then idles. At least, I think it's idling. It's
certainly not updating, and I let it run 10+ minutes.
I tried to get the history of the job and/or the logs, and I seem to be
running into snares. For example, the command $HADOOP/bin/hadoop job
-history all hadoopOutput produces the following error:
08/07/16 15:06:15 WARN fs.FileSystem: "localhost:9000" is a deprecated
filesystem name. Use "hdfs://localhost:9000/" instead.
Exception in thread "main" java.io.IOException: Not able to initialize
History viewer

I have the NameNode/TaskTracker set up via the Cluster Setup tutorial. I
have passwordless SSH, but I can't seem to get the history to work.
I've also modified the log4j.properties to include a hadooplog, but no files
are being created.
Any advice on how to get the log files and/or history working?
Thanks,
Kylie
