Hello,
I'm trying to tune terasort on a small cluster (4 identical slave
nodes w/ 4 disks and 16GB RAM each), but I'm having problems with very
uneven load.
For teragen, I specify 24 mappers, but for some reason, only 2 nodes
out of 4 run them all, even though the web UI (for both YARN and HDFS)

How can I fix the classpath to include the appropriate JAR
(hadoop-mapreduce-client-app-0.23.1-cdh4.0.0b2.jar)? It does appear to
be on the nodemanager classpath.
Thanks,

Would someone please give me some troubleshooting tips for TestDFSIO
hanging on a new 0.23.1-cdh4b2 cluster? I've tried both a 5-machine
cluster and just running everything on a single node. It's my first
time configuring YARN, so maybe I've misconfigured something. I don't
see anything suspicious
