Description

The SimpleIndexManager in the Provenance Repositories appears to leak instances of LuceneEventIndexWriter:

[nifi@machine current]$ jmap -histo:live 31598 | grep LuceneEventIndexWriter
470: 1267 30408 org.apache.nifi.provenance.lucene.LuceneEventIndexWriter$CommitStats
1266: 42 1680 org.apache.nifi.provenance.lucene.LuceneEventIndexWriter

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.
