Usually analysts will not have access to data stored in the PCI Zone, you
could write the data out to a table for the analysts by masking the
sensitive information.
Eg:
> val mask_udf = udf((info: String) => info.patch(0, "*" * 12, 7))
> val df = sc.parallelize(Seq(("user1", "400-000-444"))).toDF("user",
> "sensitive_info")
> df.show
+-----+--------------+
| user|sensitive_info|
+-----+--------------+
|user1| 400-000-444|
+-----+--------------+
> df.withColumn("sensitive_info", mask_udf($"sensitive_info")).show
+-----+----------------+
| user| sensitive_info|
+-----+----------------+
|user1|************-444|
+-----+----------------+
