Increase node-mappers capacity in single node

2011-05-27 Thread Mark question 
Hi,

  I tried changing mapreduce.job.maps to be more than 2 , but since I'm
running in pseudo distributed mode, JobTracker is local and hence this
property is not changed.

  I'm running on a 12 core machine and would like to make use of that ... Is
there a way to trick Hadoop?

I also tried using my virtual machine name instead of localhost, but no
luck.

Please help,
Thanks,
Mark

Hello Mark,

This is due to a default configuration (tasktracker slots, as we
generally call it) and is covered in the FAQ:
