[SPARK-17783] [SQL] Hide Credentials in CREATE and DESC FORMATTED/EXTENDED a PERSISTENT/TEMP Table for JDBC by gatorsmile · Pull Request #15358 · apache/spark

gatorsmile · 2016-10-05T04:51:35Z

What changes were proposed in this pull request?

We should never expose the Credentials in the EXPLAIN and DESC FORMATTED/EXTENDED command. However, below commands exposed the credentials.

In the related PR: #10452

URL patterns to specify credential seems to be vary between different databases.

Thus, we hide the whole url value if it contains the keyword password. We also hide the password property.

Before the fix, the command outputs look like:

CREATETABLEtab1
USING org.apache.spark.sql.jdbc
OPTIONS (
url 'jdbc:h2:mem:testdb0;user=testUser;password=testPass',
dbtable 'TEST.PEOPLE',
user 'testUser',
password '$password')
DESC FORMATTED tab1
DESC EXTENDED tab1

Before the fix,

Can you also put after the fix behavior in the description?

rxin · 2016-10-05T07:58:00Z


 override def toString: String = {
+ val maskedProperties = properties.map {
+ case (password, _) if password.toLowerCase == "password" => (password, "###")


I think you should rename the variable "password" to just key. For a moment I thought that was the password. Same thing with url.
Also in the case of URL, do we really want to hide the URL completely? Can't we just hide the password?

Yeah, you are right.
At the beginning, I also thought maybe we just need to hide the password value instead of hiding the whole URL. Later, when I read another PR: #10452, I thought maybe we can hide the whole url. After rethinking it, users might need to see the other field values. Will follow your suggestions to hide password values only. Thanks!

In Oracle, the specification of password and user in url does not follow the same pattern we expect. Below is an example:
jdbc:oracle:thin:scott/tiger@localhost:1521:orcl
The reference link: http://docs.oracle.com/cd/B28359_01/java.111/b31224/urls.htm
So far, the dialect does not help. Let me know whether we should add more code changes for utilizing dialects. Thanks! @rxin

rxin · 2016-10-05T07:58:47Z

+ * for JDBC data sources.
+ */
+ def maskCredentials(options: Map[String, String]): Map[String, String] = {
+ options.map {


we should consolidate this code path with the one above. Otherwise the two will diverge over time. Perhaps add them to some utils class?

Great idea! I did not find a good place to combine both. Will add it into util class

@rxin Sorry, I did not finish the PR description last night. The connection was broken in the train. Will fix it soon.
