-------------------------------------

             Summary: 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


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?
