---------------------------------
Summary: PutHive3Streaming processor Mem Leak (was: PutHive3Streaming
processor )
> PutHive3Streaming processor Mem Leak
> ------------------------------------
>
> Key: NIFI-5841
> URL: https://issues.apache.org/jira/browse/NIFI-5841
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.8.0, 1.7.1
> Environment: Hive 3.1.*
> Reporter: Advith Nagappa
> Priority: Major
>
> Nifi versions: 1,7.1 and 1.8.0
> nifi/nifi-nar-bundles/nifi-hive-bundle/nifi-hive3-processors/src/main/java/org/apache/nifi/processors/hive/PutHive3Streaming.java**
> , line 417 seems redundant,
> {code:java}
> ShutdownHookManager.addShutdownHook(hiveStreamingConnection::close,
> FileSystem.SHUTDOWN_HOOK_PRIORITY + 1){code}
>
> Whereas, Hive 3.0.0 did not addShutDownHook within connect() method, Hive
> 3.1.* does:
>
> hive/streaming/src/java/org/apache/hive/streaming/HiveStreamingConnection.java
>
> {code:java}
> ShutdownHookManager.addShutdownHook(streamingConnection::close,
> FileSystem.SHUTDOWN_HOOK_PRIORITY + 1);{code}
> This creates two references to the shutdownhook object per transaction out of
> which only one is ever removed and slow/fast degradation of heap space
> depending on the velocity of transactions.
