Enclosing class:

ApiHdfsReplicationArguments

public static enum ApiHdfsReplicationArguments.ReplicationStrategy
extends Enum<ApiHdfsReplicationArguments.ReplicationStrategy>

The strategy for distributing the file replication tasks among the mappers of the MR job associated with a replication.

Enum Constant Summary

Enum Constants

Enum Constant and Description
DYNAMIC Distributes file replication tasks in small sets to the mappers, and as each mapper is done processing its set of tasks, it picks up and processes the next unallocated set of tasks.
STATIC Distributes file replication tasks among the mappers up front, trying to achieve a uniform distribution based on the file sizes.

Enum Constant Detail

STATIC

public static final ApiHdfsReplicationArguments.ReplicationStrategy STATIC

Distributes file replication tasks among the mappers up front, trying to achieve a uniform distribution based on the file sizes.

DYNAMIC

public static final ApiHdfsReplicationArguments.ReplicationStrategy DYNAMIC

Distributes file replication tasks in small sets to the mappers, and as each mapper is done processing its set of tasks, it picks up and processes the next unallocated set of tasks.

Method Detail

values

public static ApiHdfsReplicationArguments.ReplicationStrategy[] 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 (ApiHdfsReplicationArguments.ReplicationStrategy c : ApiHdfsReplicationArguments.ReplicationStrategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static ApiHdfsReplicationArguments.ReplicationStrategy 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
