Resolution: Fixed
> Fix SPI Service File Overwriting in kudu-subprocess Shadow JAR
> --------------------------------------------------------------
>
> Key: KUDU-3768
> URL: https://issues.apache.org/jira/browse/KUDU-3768
> Project: Kudu
> Issue Type: Bug
> Reporter: Abhishek Chennaka
> Assignee: Abhishek Chennaka
> Priority: Major
> Fix For: 1.19.0
>
>
> The {{kudu-subprocess}} module's build configuration does not handle Service
> Provider Interface (SPI) merging correctly after the last gradle upgrade.
> When multiple dependencies (specifically {{jersey-core}} and
> {{{}jersey-json{}}}) provide the same registration file at
> {{{}META-INF/services/javax.ws.rs.ext.MessageBodyReader{}}}, the Shadow
> plugin's default behavior is to overwrite the file rather than append to it.
> *Root Cause:* In the current build, {{{}jersey-json{}}}'s service file
> overwrites {{{}jersey-core{}}}'s. As a result, the
> {{com.sun.jersey.core.impl.provider.entity.StringProvider}} registration is
> lost.
> *Symptoms:* When Kudu attempts to refresh policies or roles via the Ranger
> plugin, the Java subprocess logs the following error and fails to update its
> policy cache:
> {code:java}
> com.sun.jersey.api.client.ClientHandlerException: A message body reader for
> Java class java.lang.String, and Java type class java.lang.String, and MIME
> media type application/json was not found
> at
> com.sun.jersey.api.client.ClientResponse.getEntity(ClientResponse.java:630)
> ...
> SEVERE: The registered message body readers compatible with the MIME media
> type are:
> application/json ->
> com.sun.jersey.json.impl.provider.entity.JSONJAXBElementProvider$App ...
> (Note: StringProvider is missing from this list)
> {code}
> This could prevent the Kudu Master from ever receiving authorized policies
> from Ranger, leading to {{Not Authorized}} errors (403) for legitimate user
> requests.
