------------------------------------
Summary: NiFi Hive3Streaming memory leak
Key: NIFI-12148
URL: https://issues.apache.org/jira/browse/NIFI-12148
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.23.2, 1.19.1

JVM heap size is constantly grows when using Hive3Streaming processor,
depending on flowfile rate (higher rate -> faster growing). Even when processor
is stopped (or deleted) memory is not freed.
Without Hive3Streaming processor - no leaks.
Hadoop: 3.3.6, Hive 4.0.0-beta-1, NiFi - 1.23.2
Also tried: Hadoop 3.3.6, Hive 3.1.2, NiFi - 1.19.1 - same issue.
I create jvm memory dump with Jmap and with Eclipse Memory Analyzer these
results:
