Joseph Witt commented on NIFI-2677:
-----------------------------------
Peter,
My concern is that the feature is proposed as a solution (restart) to a symptom
(hung thread) that has impacts well beyond the specific problem (all parts of
the flow are impacted on a restart). We should focus on providing solutions to
finding and resolving the root cause that led to the hung thread and moving
beyond. Thread dumps are an important tool to finding the issue. And we can
do a far more surgical approach to resolution here. For instance, we can
quarantine the thread into a "here is where threads are that stopped being
effective" pile. We can isolate/neutralize their process sessions, close of
any streams, and access to any parts of the flow such that even if they do
awaken they could do no real damage or introduce any inconsistencies.
Thanks
Joe
