java.lang.Enum<ThrowableType>

org.apache.flink.runtime.throwable.ThrowableType

All Implemented Interfaces:

Serializable, Comparable<ThrowableType>

public enum ThrowableType
extends Enum<ThrowableType>

Enum for the classification of Throwable objects into failure/recovery classes.

Enum Constant Summary

Enum Constants

Enum Constant	Description
EnvironmentError	This indicates an error related to the running environment, such as hardware error, service issue, in which case we should consider blacklisting the machine.
NonRecoverableError	This indicates error that would not succeed even with retry, such as DivideZeroException.
PartitionDataMissingError	Data consumption error, which indicates that we should revoke the producer.
RecoverableError	This indicates a problem that is recoverable.

Method Summary

Modifier and Type	Method	Description
static ThrowableType	valueOf(String name)	Returns the enum constant of this type with the specified name.
static ThrowableType[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Details

NonRecoverableError

public static final ThrowableType NonRecoverableError

This indicates error that would not succeed even with retry, such as DivideZeroException. No recovery attempt should happen for such an error. Instead, the job should fail immediately.

PartitionDataMissingError

public static final ThrowableType PartitionDataMissingError

Data consumption error, which indicates that we should revoke the producer.

EnvironmentError

public static final ThrowableType EnvironmentError

This indicates an error related to the running environment, such as hardware error, service issue, in which case we should consider blacklisting the machine.

RecoverableError

public static final ThrowableType RecoverableError

This indicates a problem that is recoverable.

Method Details

values

public static ThrowableType[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ThrowableType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
