(I manged to run TaskTracker properly as in <http://answers.mapr.com/questions/1728/jobtracker-does-not-start-any-tasks> and found  another issue then.)

I installed M3 version and tried the example wordcount job.
It seems working fine now but
tasktracker logs some wired errors(?) everytime like the following.

This is regarded as INFO. can be ignored ?
