Faiz Halde commented on SPARK-45255:
------------------------------------
it seems to be failing on another issue now
a fresh project with build.sbt
```
resolvers += "snaps" at "https://repository.apache.org/snapshots/";
libraryDependencies += "org.apache.spark" %% "spark-sql-api" % "3.5.1-SNAPSHOT"
libraryDependencies += "org.apache.spark" %% "spark-connect-client-jvm" %
"3.5.0-SNAPSHOT"
```

> I know the connect does a bunch of shading during assembly so it could be
> related to that. This application is not started via spark-submit or
> anything. It's not run neither under a `SPARK_HOME` ( I guess that's the
> whole point of connect client )
>
> EDIT
> Not sure if it's the right mitigation but explicitly adding guava worked but
> now I am in the 2nd territory of error
