-----------------------------------
Summary: FlameGraphs in 1.14 do not aggregate subtasks' stack
traces anymore
Key: FLINK-24769
URL: https://issues.apache.org/jira/browse/FLINK-24769
Project: Flink
Issue Type: Bug
Components: Runtime / Web Frontend
Affects Versions: 1.14.0
Reporter: Nico Kruber
Attachments: image-2021-11-04-12-59-24-308.png
Since Flink 1.14.0, after enabling FlameGraphs and gathering statistics for a
task, it doesn't aggregate the results from the parallel instances anymore but
instead shows each individual one - something that easily gets too messy for
higher parallelism.
It seems the last shared method on the stack is
{{Task.runWithSystemExitMonitoring}} and then it spawns off into individual
lambda functions:
