Method Detail

immutableWithResources

public static ModifiableHadoopConfiguration immutableWithResources()

Returns a ModifiableHadoopConfiguration backed by a an immutable Hadoop Configuration with default resources loaded (e.g. the contents of core-site.xml, core-default.xml, mapred-site.xml, ...). Immutability is guaranteed by encapsulating the Hadoop Configuration in a forwarder class that throws exceptions on data modification attempts. Reads are supported though.

Returns:

withoutResources

public static ModifiableHadoopConfiguration withoutResources()

of

public static ModifiableHadoopConfiguration of(org.apache.hadoop.conf.Configuration c)
