> Java kudu-client incorrectly declares com.stumbleupon:async as optional
> -----------------------------------------------------------------------
>
> Key: KUDU-3677
> URL: https://issues.apache.org/jira/browse/KUDU-3677
> Project: Kudu
> Issue Type: Bug
> Components: java
> Affects Versions: 1.18
> Reporter: James Netherton
> Assignee: Alexey Serbin
> Priority: Blocker
>
> There was a change in the Java kudu-client pom.xml between the 1.17.1 and
> 1.18.0 with regards to how dependency com.stumbleupon:async is declared.
> *1.17.1*
> {code:java}
> <dependency>
> <groupId>com.stumbleupon</groupId>
> <artifactId>async</artifactId>
> <version>1.4.1</version>
> <scope>compile</scope>
> <exclusions>
> <exclusion>
> <artifactId>slf4j-api</artifactId>
> <groupId>org.slf4j</groupId>
> </exclusion>
> </exclusions>
> </dependency>
> {code}
> *1.18.0*
> {code:java}
> <dependency>
> <groupId>com.stumbleupon</groupId>
> <artifactId>async</artifactId>
> <version>1.4.1</version>
> <scope>compile</scope>
> <exclusions>
> <exclusion>
> <groupId>org.slf4j</groupId>
> <artifactId>slf4j-api</artifactId>
> </exclusion>
> </exclusions>
> <optional>true</optional>
> </dependency>
> {code}
> Note the addition of <optional> in 1.18.0.
> Looking at the code from KuduClient and AsyncKuduClient, there are various
> references to Deferred & Callback types. If you try to invoke methods that
> use those types, then you'll get ClassNotFoundException. Unless you add the
> missing com.stumbleupon:async dependency to the classpath.
> Can the previous non-optional dependency declaration be restored for future
> releases?
