Subject map JVMs do not cease to exist
Date Tue, 29 Mar 2011 20:08:49 GMT
Noticed this on a TeraSort run - map JVM processes do not exit/cease to
exist even after a long while from successful execution of all map tasks.
Resources consumed by these JVM processes do not seem to be relinquished
either and that causes poor performance in the rest of the reduce phase
which continues execution after map phase is done.

Do you see this as an issue? If so, is it a known issue?
