vinoyang commented on FLINK-11103: ---------------------------------- Oh, I see you mentioned FLINK-5232, and it mainly adds exception catching to the thread pool of the actor system's dispatcher. So, I thought this is the same as the issue. However, I think your consideration is reasonable. In addition to the actor system, TM still uses threads in many places. > Set a default uncaught exception handler > ---------------------------------------- > > Key: FLINK-11103 > URL: https://issues.apache.org/jira/browse/FLINK-11103 > Project: Flink > Issue Type: Improvement > Components: TaskManager > Affects Versions: 1.8.0 > Reporter: Nico Kruber > Assignee: vinoyang > Priority: Major > > We should set a default uncaught exception handler in Flink via > {{Thread.setDefaultUncaughtExceptionHandler()}} which at least logs the > exceptions. Ideally, we would even fail the job (could make this > configurable) but users may have some ill-behaving threads, e.g. through > libraries, which they would want to tolerate and we don't want to change > behaviour now. > (FLINK-5232 added this for the JobManager, we need it for the TaskManager) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
