How Do I Set the AK/SK for a Queue to Operate an OBS Table?

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()

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.
