      • RETRY_AFTER_TWO_SECONDS_FOREVER

        public static final BlockFetchFailureProperty.Value RETRY_AFTER_TWO_SECONDS_FOREVER
        Do not cancel the running task. Instead, retry fetching the data block two seconds after the fetch failure. We wait two seconds in the hope that the parent task will be re-scheduled by the master, and make the block "available" again. Upon the failure of the retry, we retry again. (i.e., we retry forever)

      • values

        public static BlockFetchFailureProperty.Value[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (BlockFetchFailureProperty.Value c : BlockFetchFailureProperty.Value.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static BlockFetchFailureProperty.Value valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
