The temporary AK/SK is recommended. For details, see Obtaining a Temporary Access Key and Security Token in Identity and Access Management API Reference.

If the AK and SK are obtained, set the parameters as follows:

Create SparkContext using code

val sc: SparkContext = new SparkContext()
sc.hadoopConfiguration.set("fs.obs.access.key", ak)
sc.hadoopConfiguration.set("fs.obs.secret.key", sk)

Create SparkSession using code

val sparkSession: SparkSession = SparkSession
      .builder()
      .config("spark.hadoop.fs.obs.access.key", ak)
      .config("spark.hadoop.fs.obs.secret.key", sk)
      .enableHiveSupport()
      .getOrCreate()

If ak, sk, and securitytoken are obtained, the temporary AK/SK and security token must be used at the same time during authentication. The setting is as follows:

Create SparkContext using code

val sc: SparkContext = new SparkContext()
sc.hadoopConfiguration.set("fs.obs.access.key", ak)
sc.hadoopConfiguration.set("fs.obs.secret.key", sk)
sc.hadoopConfiguration.set("fs.obs.session.token", sts)

Create SparkSession using code

val sparkSession: SparkSession = SparkSession
      .builder()
      .config("spark.hadoop.fs.obs.access.key", ak)
      .config("spark.hadoop.fs.obs.secret.key", sk)
      .config("spark.hadoop.fs.obs.session.token", sts)
      .enableHiveSupport()
      .getOrCreate()

NOTE:

For security purposes, you are advised not to include the AK and SK information in the OBS path. In addition, if a table is created in the OBS directory, the OBS path specified by the Path field cannot contain the AK and SK information.
