jason updated NIFI-9767:
------------------------
Description:
PutKudu 1.15.0 eats up all the heap memory. Must restart NiFi to free heap.
We create twenty the same of pipelines for test, will out of memory on few
hours.Pipeline as shown in pipeline.png
This test scenario is to reproduce the OOM error (-Xms4G、-Xmx4G)
In fact, found this issue because we have built some data pipelines including
five putkudu processors(
-Xms12G、-Xmx12G). It is found that the heap cannot be free and the number of
threads continues to increase until OOM(After 8 hours). After analysis, it is
found that it is a problem with the putkudu processor. We are confused why the
heap is not freed automatically and there are more and more threads
