Error in starting hadoop Job Tracker

Question

I tried to run a simple program in hadoop using Windows-Cygwin.

I am able to start the namenode .

The jobtracker start however fails with exception :

<         


        

Answer 1

The problem is the following lines should on into mapred-site.xml and NOT hdfs-site.xml,

 
mapred.job.tracker 
localhost:9101 

By the way why are you trying to run Hadoop in Windows? For development? You don't have a linux machine or reluctant to install one?

One more thing, you usually put this property in core-site.xml not hdfs-site.xml,

fs.default.name
hdfs://localhost:9100
