Hadoop Nodemanager and Resourcemanager not starting

问题

I am trying to setup the latest Hadoop 2.2 single node cluster on Ubuntu 13.10 64 bit. the OS is a fresh installation, and I have tried using both java-6 64 bit and java-7 64 bit.

After following the steps from this and after failing, from this link, I am not able to start nodemanager and resourcemanager with the command:

sbin/yarn-daemon.sh start nodemanager
sudo sbin/yarn-daemon.sh start nodemanager

and resource manager with

sbin/yarn-daemon.sh start resourcemanager
sudo sbin/yarn-daemon.sh start resourcemanager

and both fails with error:

starting nodemanager, logging to /home/hduser/yarn/hadoop-2.2.0/logs/yarn-hduser-nodemanager-ubuntu.out

Resource Manager fails with similar error: NoClassDefFoundError

I have been trying this for many hours and have tried Google and nothing worked. Please let me know what I have missed. This and this link while searching for a solution didn't work.

I have tried using both java-6 and java-7 64 bit, with no success.

Edit

The accepted answer managed to get rid of the exception and all the daemons are now starting but there is still an exception while running jobs, mentioned in this question

回答1:

Those instructions are stale and seem to reflecting one of the very early alpha releases. Make this change: YARN_HOME -> HADOOP_YARN_HOME. The environment variable got renamed a while back. This should fix it for you.

You can use Apache Ambari 1.4.1 that eases installation of Hadoop and many of its ecosystem components. You can see http://docs.hortonworks.com/#2.0 on how to install using Ambari.

you should see this is solution, add $HADOOP_HOME/share/ and its sub-directories. http://www.srccodes.com/p/article/46/noclassdeffounderror-org-apache-hadoop-service-compositeservice-shell-exitcodeexception-classnotfoundexception
