ListResources Method
Lists resources in a given directory.
Syntax
hadoopdfs.listResources(dirPath, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This method lists resources within the directory at DirPath.
Calling this method will fire the ResourceList event once for each resource, and will also populate the Resource* properties.
DirPath may be empty to list resources in the root directory (/).
// ResourceList event handler. hdfs.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; hdfs.ListResources("/work_files/serious_business/cats"); for (int i = 0; i < hdfs.Resources.Count; i++) { // Process resources here. }
