hi, I am unable to delete a folder which is not empty and getting the following error.

{"RemoteException":{"exception":"PathIsNotEmptyDirectoryException","javaClassName":"org.apache.hadoop.fs.PathIsNotEmptyDirectoryException","message":"`/aakash is non empty': Directory is not empty"}}

In order to delete a directory that has content you need to pass the recursive option as well as a callback for handling errors like so:

import WebHDFS from 'webhdfs';

const client = WebHDFS.createClient({
  host: 'example.dev.company.com',
  port: 8080,
  path: '/',
});

const deleteDirectoryWithContent = (directoryPath) => 
  client.unlink(directoryPath, true, (error) => {
    if (error) throw error;
  });
