Subject Re: Adjusting tasktracker heap size?
Date Mon, 15 Apr 2013 18:08:09 GMT
It depends on the type of job that is frequently submitting.
RAM size of the machine.
Heap size of tasktracker= (mapslots+reduceslots)*jvm size
We can adjust this according to our requirement to fine tune our cluster.
This is my thought.
