Michael W Moser updated NIFI-14959:
-----------------------------------
Description:
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.
