Advith Nagappa updated NIFI-5841:
---------------------------------
Description:
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 add ShutDownHook 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 resulting in a slow/fast degradation of heap
space depending on the velocity of transactions.
