Hi Mingjie,
I don't know about Yarn, but NoClassDefFoundError appear when you have a
class that was present during compile time but no longer available
during runtime. See a detailed explanation here [1].
Check that the classpath built in the container/node contains the
classes from that error. Also check that you don't get another version
on the classpath, one without the specified class.
Hope this helps,

Hi.
I'm trying yarn + security but still cannot make a mapred example
runing. Can anyone help me to take a look?
My env:
- 3-slave cluster on ec2. Centos 5.5
- nn, dn, rm, nm all started, with security enabled.
- i saw java.lang.NoClassDefFoundError from LinuxContainerExecutor eror
log:
./application_1330545370212_0004/container_1330545370212_0004_01_000001/stderr
- If i disable security, still saw this issue.
Any hint?
I followed the instructions from
http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/ClusterSetup.html
Steps:
I started a mapred sample from nn/rm:
$ usr/lib/hadoop/bin/yarn --config ./conf jar
share/hadoop/mapreduce/hadoop-mapreduce-examples-0.24.0-SNAPSHOT.jar
randomwriter 10 10
Logs are from nn, nm,

Running 30 maps.
