RE: Can't find main class when run ResourceManager or NodeManager
Hi,

Please configure HADOOP_COMMON_HOME and HADOOP_HDFS_HOME environment
variables.

And then start the resource manager it will start.
Reason: All the common classes will be loaded to classpath from the
HADOOP_COMMON_HOME. So Configuration class is not found in the classpath.

Regards,
Vinayakumar B.
