Key Default Type Description
cluster.intercept-user-system-exit
DISABLED

Enum

Flag to check user code exiting system by terminating JVM (e.g., System.exit()). Note that this configuration option can interfere with cluster.processes.halt-on-fatal-error: In intercepted user-code, a call to System.exit() will not cause the JVM to halt, when THROW is configured.

Possible values:
  • "DISABLED": Flink is not monitoring or intercepting calls to System.exit()
  • "LOG": Log exit attempt with stack trace but still allowing exit to be performed
  • "THROW": Throw exception when exit is attempted disallowing JVM termination
cluster.processes.halt-on-fatal-error
false Boolean Whether processes should halt on fatal errors instead of performing a graceful shutdown. In some environments (e.g. Java 8 with the G1 garbage collector), a regular graceful shutdown can lead to a JVM deadlock. See FLINK-16510 for details.
cluster.uncaught-exception-handling
LOG

Enum

Defines whether cluster will handle any uncaught exceptions by just logging them (LOG mode), or by failing job (FAIL mode)

Possible values:
  • "LOG"
  • "FAIL"
