Replace map reduce prop in continuous ingest verify
When was this property changed in Hadoop? We need to be careful we're not breaking things with the earliest Hadoop version we still support.

Honestly I'm not sure. I am having trouble finding what version this change happened in. I do see that the following code was from 13 years ago at which point this property was already deprecated.

git tag --contains 833da65d8629e0bdd79097ed26033add9fc1864f shows that it appears in at least Hadoop 3.0.0 and newer, and we don't support anything older than that anymore, so this should be good.
