The document discusses the Mule HDFS Connector configuration options. It describes the General, Connection, Config Reference, Pooling Profile, and Reconnection tabs in the configuration wizard. The General tab contains options like display name, config reference, operation, path, and buffer size. The Connection tab adds the connection key. The Config Reference tab sets properties like name, connection key, file system, and resources. The Pooling Profile tab controls pooling with properties like max active, max idle, and initialization policy. Finally, the Reconnection tab sets reconnection strategies and properties like frequency, attempts, and reconnector forever.
