A couple of comments: a) IIRC async profiler does not have a way to associate the java thread with the underlying linux thread - and so from a future evolution point of view, we cannot corelate this with a task's stack traces. Given work being done as part of SPARK-45151, is there a way to make this work with whatever @yaooqinn added support for ? b) This PR is creating one file per executor on hdfs - which would end up being very expensive as number of executors per application and number of applications increase. How are we looking to minimize this cost ? -- This is an automated message from the Apache Git Service.
