ResourceManager not getting started in 0.23
Hi,

I am making some change to the 0.23 branch and got the latest code and
successfully build it. Am able to start the NameNode and the DataNode, but
when I start the ResourceManager I am getting 'ClassNotFoundException'. The
classpath to run the ResourceManager is not getting generated properly by
the 'sbin/yarn-daemon.sh' command. I also noticed that the modules folder
is not getting created when the hadoop-0.23.1-SNAPSHOT.tar.gz is untarred.

Is this a bug or I missed something?

---------------------

sbin/yarn-daemon.sh start resourcemanager

-classpath
/home/praveensripati/Hadoop/0.23/deploy/hadoop-0.23.1-SNAPSHOT/conf/:/home/praveensripati/Hadoop/0.23/deploy/hadoop-0.23.1-SNAPSHOT/conf/:/home/praveensripati/Hadoop/0.23/deploy/hadoop-0.23.1-SNAPSHOT/conf/:/usr/lib/jvm/jdk1.6.0_27/lib/tools.jar:/usr/lib/jvm/jdk1.6.0_27/lib/tools.jar:/home/praveensripati/Hadoop/0.23/deploy/hadoop-0.23.1-SNAPSHOT/conf//rm-config/log4j.properties

Caused by: java.lang.ClassNotFoundException:
org.apache.hadoop.yarn.server.resourcemanager.ResourceManager
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)

---------------------

BTW, I am able to run the example Hadoop after downloading
hadoop-0.23.0.tar.gz from Apache.

I have the following settings in .bashrc

export
HADOOP_DEV_HOME=/home/praveensripati/Hadoop/0.23/deploy/hadoop-0.23.1-SNAPSHOT
export HADOOP_MAPRED_HOME=$HADOOP_DEV_HOME
export HADOOP_COMMON_HOME=$HADOOP_DEV_HOME
export HADOOP_HDFS_HOME=$HADOOP_DEV_HOME
export YARN_HOME=$HADOOP_DEV_HOME
export HADOOP_CONF_DIR=$HADOOP_DEV_HOME/conf/
export YARN_CONF_DIR=~$HADOOP_DEV_HOME/conf/

Praveen
