[jira] [Created] (NIFI-3631) Memory Leak in SimpleIndexManager

Mark Payne created NIFI-3631:
--------------------------------

             Summary: Memory Leak in SimpleIndexManager
                 Key: NIFI-3631
                 URL: https://issues.apache.org/jira/browse/NIFI-3631
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Mark Payne
            Assignee: Mark Payne
            Priority: Critical


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.
