Hello,

I have configured hadoop install according to instructions I found on
the internet; when I start hadoop namenode/datanode, I get:

java.lang.NoClassDefFoundError:
org/apache/hadoop/hdfs/server/namenode/NameNode
Caused by: java.lang.ClassNotFoundException:

hadoop classpath shows me:

/home/kdelia/yarn/hadoop-2.2.0/etc/hadoop:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/common/lib/*:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/common/*:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/hdfs:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/hdfs/lib/*:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/hdfs/*:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/yarn/lib/*:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/yarn/*:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/mapreduce/lib/*:/home/kdelia/yarn/hadoop-2.2.0/share/hadoop/mapreduce/*:/home/kdelia/yarn/hadoop-2.2.0/contrib/capacity-scheduler/*.jar


So, it appears that the libraries needed by the services can be found.
 Not sure why I am getting the class not found exception.

I am using instructions from this site:

Thanks!
