Summary: [ML] SVM throws NPE in case of empty partitions
Key: IGNITE-9055
URL: https://issues.apache.org/jira/browse/IGNITE-9055
Project: Ignite
Issue Type: Bug
Components: ml
Affects Versions: 2.5, 2.6
Reporter: Anton Dmitriev
Fix For: 2.7
Method `calculateUpdates` throws NPE in case of empty partitions. Reduce
function user in this method doesn't handle correctly empty arguments (`(a, b)
-> a == null ? b : a.plus(b))`).
We need to fix this reduce function or update Partition Based Dataset so that
it doesn't emit empty arguments.
