hdfs::native::hdfsBuilderSetNameNode

pub unsafe extern fn hdfsBuilderSetNameNode(bld: *mut hdfsBuilder, host: *const c_char)

Set the HDFS NameNode to connect to.

Params

• bld - The HDFS builder
• nn - The NameNode to use. If the string given is 'default', the default NameNode configuration will be used (from the XML configuration files). If NULL is given, a LocalFileSystem will be created. If the string starts with a protocol type such as file:// or hdfs://, this protocol type will be used. If not, the hdfs:// protocol type will be used. You may specify a NameNode port in the usual way by passing a string of the format hdfs://<hostname>:<port>. Alternately, you may set the port with hdfsBuilderSetNameNodePort. However, you must not pass the port in two different ways.
