Summary: Parfor spark fair scheduler pool leak
Key: SYSTEMML-2175
URL: https://issues.apache.org/jira/browse/SYSTEMML-2175
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
In an algorithm with an overall convergence loop and a parfor loop over large
data in each outer iteration, we encountered a leak of parfor fair scheduler
pools. Specifically, this issue seems to arise whenever the parfor loop has
fewer iterations and thus workers than locally available threads.
