public static final MarkerType DIRECT

TIMELINE_SERVER_BASED

@EnumFieldDescription(value="Marker operations are all handled at the timeline service which serves as a proxy. New marker entries are batch processed and stored in a limited number of underlying files for efficiency. If HDFS is used or timeline server is disabled, DIRECT markers are used as fallback even if this is configured. This configuration does not take effect for Spark structured streaming; DIRECT markers are always used.")
public static final MarkerType TIMELINE_SERVER_BASED

Method Detail

values

public static MarkerType[] values()

    System.out.println(c);

Returns:

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

valueOf

public static MarkerType 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:
