Thank you! Just to confirm. Consider a JVM (that is being reused), has
to reduce K1,{V11,V12,V13..} and K2,{V21,V22,V23,}. Then the
configure and close methods are called once each for both K1,{V11,...}
and K2,{V2,}?
Is my understanding correct?
Once again, there is no combiner, and it
configure and close are run for each task, mapper and reducer. The configure
and close are NOT run on the combiner class.

Hello,
In a mapreduce job, a given map JVM will run N map tasks. Are the
