Key Default Type Description
cluster.evenly-spread-out-slots
false Boolean Enable the slot spread out allocation strategy. This strategy tries to spread out the slots evenly across all available TaskExecutors.
cluster.fine-grained-resource-management.enabled
false Boolean Defines whether the cluster uses fine-grained resource management.
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.io-pool.size
(none) Integer The size of the IO executor pool used by the cluster to execute blocking IO operations (Master as well as TaskManager processes). By default it will use 4 * the number of CPU cores (hardware contexts) that the cluster process has access to. Increasing the pool size allows to run more IO operations concurrently.
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.registration.error-delay
10000 Long The pause made after an registration attempt caused an exception (other than timeout) in milliseconds.
cluster.registration.initial-timeout
100 Long Initial registration timeout between cluster components in milliseconds.
cluster.registration.max-timeout
30000 Long Maximum registration timeout between cluster components in milliseconds.
cluster.registration.refused-registration-delay
30000 Long The pause made after the registration attempt was refused in milliseconds.
cluster.services.shutdown-timeout
30000 Long The shutdown timeout for cluster services like executors in milliseconds.
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"
fine-grained.shuffle-mode.all-blocking
false Boolean Whether to convert all PIPELINE edges to BLOCKING when apply fine-grained resource management in batch jobs.
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.
