> 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?
