Hi All ,
I have multinode cluster with 1 master (namenode,+ jobtracker) and
2 slavers (datanode + tasktracker).
I can start namenode and datanodes,but CANT start jobtracker.The
log shows java.lang.NumberFormatException.
I will be greatfull if anybody can tell me what is the problem and
why is this java execption being thrown?
here is the complete log , all the files value are
attached.(master,slaves,core-site.xml...etc)
