> I'm running a task which is throwing the following exception during the Map phase:
> {noformat}
> org.infinispan.util.concurrent.TimeoutException: Node main-NodeC-22183 timed out{noformat}
> The user facing error however is this very confusing message:
> {noformat}org.infinispan.commons.CacheException: java.util.concurrent.ExecutionException: Map phase executing at main-NodeA-39904 did not complete within 0 sec timeout{noformat}
> I have no timeout enabled.
> The problem is the instanceof operation on the cause of the error in org.infinispan.distexec.mapreduce.MapReduceTask.executeMapPhaseWithLocalReduction(Map<KOut, VOut>): the check on the type only is not good enough.
