Hello, I am using apache hadoop-1.0.3 version and i want to commission a task tracker. For this i have included a property mapred.hosts in mapred-site.xml and for this property i have mentioned a file. In this file i have given the IP address of a machine..
then i ran the command "hadoop mradmin -refreshNodes" Now what i see, when i am trying to run the task tracker on that machine, it is throwing me an exception that task tracker is not allowed to communicate with the job tracker... I have used the newer property (mapred.jobtracker.hosts.filename) even this was not helpful and more over this property is not recognized by the job tracker. Please advise me how to commission a task tracker Regards, Som Shekhar Sharma +91-8197243810
