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.thread-dump.stacktrace-max-depth
8 Integer The maximum stacktrace depth of TaskManager and JobManager's thread dump web-frontend displayed.
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"
process.jobmanager.working-dir
(none) String Working directory for Flink JobManager processes. The working directory can be used to store information that can be used upon process recovery. If not configured, then it will default to process.working-dir.
process.taskmanager.working-dir
(none) String Working directory for Flink TaskManager processes. The working directory can be used to store information that can be used upon process recovery. If not configured, then it will default to process.working-dir.
process.working-dir
io.tmp.dirs String Local working directory for Flink processes. The working directory can be used to store information that can be used upon process recovery. If not configured, then it will default to a randomly picked temporary directory defined via io.tmp.dirs.
