Support federation to Presto using JWT authentication

Customer does not allow user/password authentication to data sources, including Db2 and Presto ( With the help from the labs we managed to configure Presto in to accept JWT authentication; for this an idea has been created ( In order to make the querying of offloaded Db2 data to as transparent as possible for the end-users, we need single sign-on from Db2 to Presto.

We have been able to use the Presto certificate and configure JWT authentication for Db2, but we cannot successfully create a Federation Server NICKNAME for a Presto table; this fails because of invalid parameters in the JDBC connection string.

Message from Tony Liu (Db2 Federation Server development):
Using the connection properties (accessToken, accessTokenType, securityMechanism) that we hard-coded in Federation JDBC wrapper for constructing connection  strings for Db2 JWT to connect to Presto I get following error:

java.sql.SQLException: Unrecognized connection property 'accessTokenType' at com.facebook.presto.jdbc.PrestoDriverUri.validateConnectionProperties( at com.facebook.presto.jdbc.PrestoDriverUri.<init>( at com.facebook.presto.jdbc.PrestoDriverUri.<init>( at com.facebook.presto.jdbc.PrestoDriver.connect( at java.sql/java.sql.DriverManager.getConnection( at java.sql/java.sql.DriverManager.getConnection(

This seems rather a valid error message reported by Presto JDBC driver. And since Federation needs to get the JWT token from Db2 engine and I don' think there are other workaround. So this leads us to the conclusion that to support Presto JWT authentication Db2 engine (Federation) code change is required. Please ask customer to open RFE to us.
