How to load typesafe configFactory from file on hdfs?

Using ConfigFactory.parseReader should work (but I haven't tested it):

val reader = new InputStreamReader(file)val config = try {  ConfigFactory.parseReader(reader)} finally {  reader.close()}

You should be able to load .conf file in hdfs using the following code:

ConfigFactory.parseFile(new File("application.conf"));

Please keep in mind that the .conf file should be placed on the same directory as your app file (e.g. jar file in spark).

Here is what I did with Spark application:

  /**    * Load typesafe's configuration from hdfs file location    * @param sparkContext    * @param confHdfsFileLocation    * @return    */  def loadHdfsConfig(sparkContext: SparkContext, confHdfsFileLocation: String) : Config = {    // Array of 1 element (fileName, fileContent)    val appConf: Array[(String, String)] = sparkContext.wholeTextFiles(confHdfsFileLocation).collect()    val appConfStringContent = appConf(0)._2    ConfigFactory.parseString(appConfStringContent)  }

Now in the code, just use

val config = loadHdfsConfig(sparkContext, confHdfsFileLocation)config.getString("key-here")

I hope it helps.
