...ANSWER
Answered 2021-Dec-27 at 11:08You can't use connector compiled for Scala 2.11 with Spark 3.2.0 that is compiled with Scala 2.12. You need to use appropriate version - right now it's 3.1.0 with coordinates com.datastax.spark:spark-cassandra-connector_2.12:3.1.0
P.S. Please note that although basic functionality will work, more advanced functionality won't work until the SPARKC-670 is fixed (see this PR)
QUESTION
I have created an authorization server using the new spring authorization server module. I am able to get the token successfully but when I try to use the token against a protected endpoint with hasAuthority()
I get forbidden 403 error. Below my pom.xml
file
ANSWER
Answered 2021-Dec-18 at 14:57Based on a brief discussion in comments to clarify your setup, it seems that you are configuring your authorization server as a regular secured application with the intention of using scopes as authorities. However, this is an incorrect usage of the authorization server.
Note: I have not seen any reference to an OAuth 2.0 client or resource server in your description, so I'm assuming you are trying to hit endpoints directly on the authorization server. If that's not the case, let me know.
There are three applications involved in an OAuth 2.0 protected setup:
- Authorization server
- Resource server
- Client
Your configuration is only for #1 (as far as I can tell). The authorization server contains two filter chains and additionally a configuration for a single oauth client. The two filter chains do the following:
- Secure endpoints provided by the authorization server framework
- Secure the login endpoint(s) the user will interact with prior to using the authorization endpoint (
/oauth2/authorize
) to obtain an authorization code, which the client will later use to obtain an access token
The scopes you have configured would allow a user (resource owner) to grant an oauth client the ability to make a protected call to a resource server using an access token. Only when the client makes a call to a resource server will your configured scopes be used. When the user directly interacts with an endpoint on the authorization server using a browser, the configuration for form login is in play, which as I mentioned in comments, uses roles from your database.
See the SpringOne 2021 repository and presentation to understand how to take an application from an unsecured application to a secured one, and then see how we turn it into a resource server, which uses scopes as authorities.
The presentation demonstrates all three applications, though the focus is on the resource server, which matches closely what you are trying to accomplish with scopes as authorities.

Answered 2021-Aug-30 at 22:24The problem here is not schema, or lack thereof (kind of), but rather that you are constructing new ObjectWriter

Instead, you need to construct a SequenceWriter

QUESTION
EDIT: Although yukim's workaround does work, I found that by downgrading to JDK 8u251 vs 8u261, the sigar lib works correctly.
- Windows 10 x64 Pro
- Cassandra 3.11.7
NOTE: I have JDK 11.0.7 as my main JDK, so I override JAVA_HOME and PATH in the batch file for Cassandra.
Opened admin prompt and...
java -version
...ANSWER
Answered 2020-Jul-29 at 01:05I think it is sigar-lib that cassandra uses that is causing the problem (especially on the recent JDK8).
It is not necessary to run cassandra, so you can comment out this line from cassandra-env.ps1 in conf directory: https://github.com/apache/cassandra/blob/cassandra-3.11.7/conf/cassandra-env.ps1#L357

list of libs:
...ANSWER
Answered 2020-Jun-23 at 07:54There are conflict libraries.
You said in your question that you are using jackson-core-2.10.3.jar
And in your dependency list, I see jackson-core-2.10.3.jar
Two different versions causing the conflict. It could probably be transitive dependency. Exclude the one you don't need.
