In hadoop= 1.2/1.0 , following is the property =A0
 <property>
    <name>mapred.hosts</name>
    <value>${HADOOP_CONF_DIR}/mapred.include</value>

Hello,
I am = using apache hadoop-1.0.3 version and i want to commission a task tracker.<= /div>
For this i have included a property mapred.hosts in mapred-site.xml an= d 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 =A0 "hadoop mradmin -refres= hNodes"

Now what i see, when i am trying to r= un the task tracker on that machine, it is throwing me an exception that ta= sk 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 rec= ognized by the job tracker.

Please advise me how t= o commission a task tracker
