> [nifi@machine current]$ jmap -histo:live 31598 | grep LuceneEventIndexWriter
>  470:          1267          30408  org.apache.nifi.provenance.lucene.LuceneEventIndexWriter$CommitStats

> We should have 1-2 Index Writers per prov partition, and this node has 2 prov partitions but we see 42 instances of the LuceneEventIndexWriter.
