Summary: Allow non-emitting Mapper
Key: ISPN-2353
URL: https://issues.jboss.org/browse/ISPN-2353
Project: Infinispan
Issue Type: Bug
Components: Distributed Execution and Map/Reduce
Affects Versions: 5.2.0.Alpha4
Reporter: Vladimir Blagojevic
Assignee: Vladimir Blagojevic
Fix For: 5.2.0.Beta1, 5.2.0.Final
In some cases Mapper being executed on remote nodes might not produce any intermediate
KOut/VOut pairs and we should allow/account for that possibility. Currently such tasks
fail with NPE.

-------------------------------------------
We can attempt to mitigate these kinds of situations but it is better to make a generic
fix - wait for full cache startup before allowing incoming remote invocations.

Mircea Markus commented on ISPN-2353:
-------------------------------------
As per the email thread posted by Vladimir this seems to be caused when async clusters are
used.
We already offer support for async clusters(ISPN-658), so we should handle this situation
for map reduce as well.
Basically before launching the M/R task we should check if the cache is started locally.
If it isn't we shouldn't start it.
