Unable to upgrade the Schema Registry via yum

Hi all,

I have a running Confluent 4.0.0 stack and would like to upgrade to the latest (4.1.0). After updating the repository URLs, if I run

yum update confluent-schema-registry

the package is updated to the 4.1.0, but when starting the schema registry daemon I get this classpath error:

at io.confluent.kafka.schemaregistry.rest.SchemaRegistryMain.main(SchemaRegistryMain.java:43)
at io.confluent.rest.Application.createServer(Application.java:157)

Exception in thread "main" java.lang.NoSuchMethodError: io.confluent.kafka.schemaregistry.rest.SchemaRegistryConfig.getMap(Ljava/lang/String;)Ljava/util/Map;

In fact, if I check the installed confluent versions I find:

yum list installed | grep confluent
confluent-common.noarch            4.0.0-1                        @Confluent
confluent-kafka-2.11.noarch        1.1.0-1                        @Confluent
confluent-rest-utils.noarch        4.0.0-1                        @Confluent
confluent-schema-registry.noarch   4.1.0-1                        @Confluent

So the yum update of the schema registry did not update the dependencies. I checked the dependencies of the package and found that it references the confluent-rest-utils package without a required version

yum deplist confluent-schema-registry
package: confluent-schema-registry.noarch 4.1.0-1
  dependency: confluent-rest-utils
   provider: confluent-rest-utils.noarch 4.1.0-1

This is different by, for example, the kernel yum package, where some dependencies target a specific version

yum deplist kernel
package: kernel.x86_64 3.10.0-693.21.1.el7
  dependency: module-init-tools >= 3.16-2
   provider: kmod.x86_64 20-15.el7_4.7

Do you think that the Confluent's yum packages should point to a specific version of the dependencies in order to let the yum update command update all the dependencies together?

confluentinc / schema-registry
