bharos opened a new issue, #8754:
URL: https://github.com/apache/gravitino/issues/8754
### Version
main branch
### Describe what's wrong
Client to server connection is not happening ,and it is returning the error
shown in stack trace below
### Error message and/or stacktrace
Spark client on connecting to Icebeg Rest catalog in Gravitino gives the
error:
```
at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)
Exception in thread "main"
org.apache.iceberg.exceptions.ServiceFailureException: Server error: null: {
"servlet":"org.glassfish.jersey.servlet.ServletContainer-602f8f94",
"message":"org.glassfish.jersey.server.ContainerException:
java.lang.NoSuchMethodError: 'void
org.apache.hadoop.security.HadoopKerberosName.setRuleMechanism(java.lang.String)'",
"url":"/iceberg/v1/config",
"status":"500"
}
```
Looking at the jars on Gravitino server, seems like there's a mix of hadoop
2.x and 3.x which is causing the class conflicts
```
kubectl exec deployment/gravitino -n hms3 -- find /r
oot -name "*hadoop*" -type f | head -10
