Method Detail

deepCopy

public static Properties deepCopy(Properties properties)

Use this to deep copy properties. The copy constructor in Properties does not do a deep copy.

Parameters:

properties -

Returns:

new mutable instance of Properties populated with values from the passed in Properties.

public static Properties combineProperties(Properties props,
                           org.apache.hadoop.conf.Configuration conf)

Add properties from the given Configuration to the provided Properties. Note that only those configuration properties will be added to the provided properties whose values are already not set. The method doesn't modify the passed in properties instead makes a clone of them before combining.

Returns:

properties object that is a combination of properties contained in props and properties contained in conf

cloneConfig

public static org.apache.hadoop.conf.Configuration cloneConfig(org.apache.hadoop.conf.Configuration toCopy)

Parameters:

toCopy - configuration to copy

Returns:
