Michael W Moser updated NIFI-14959:
-----------------------------------
Summary: Partition by attribute load balance strategy sends 0 files to one
node (was: Partition by attribute load balance strategy favors 1 node with
more files)
> Partition by attribute load balance strategy sends 0 files to one node
> ----------------------------------------------------------------------
>
> Key: NIFI-14959
> URL: https://issues.apache.org/jira/browse/NIFI-14959
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Andreas Koch
> Assignee: Michael W Moser
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> CorrelationAttributePartitioner.findIndex always returns 0 if partitions == 2
> Ways to reproduce. Added static to findIndex
>
> {code:java}
> for (int i = Integer.MIN_VALUE; i < Integer.MAX_VALUE; i++) {
> int idx = findIndex(i, 2);
> if (idx != 0) {
> System.out.println(i);
> }
> } {code}
> Assuming the attribute value for "Partition by attribute" would result in an
> even distribution, the node at index 0 receives roughly 2/N flowfiles, one
> node receives 0 flowfiles, and the other nodes receive 1/N flowfiles.
