LOCAL

public static final ExecType LOCAL
Run everything on the local machine


MAPREDUCE

public static final ExecType MAPREDUCE
Use the Hadoop Map/Reduce framework

Method Detail

values

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

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

valueOf

public static ExecType 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

fromString

public static ExecType fromString(String execString)
                           throws PigException
Given a string, determine the exec type.

Parameters:
execString - accepted values are 'local', 'mapreduce', and 'mapred'
Returns:
exectype as ExecType
Throws:
PigException
