Subject Re: Kinesis Connector Dependency Problems
Date Tue, 08 Nov 2016 10:11:19 GMT

Which Maven version are you using?
Maven 3.3.x does not properly shade dependencies.
You have to use Maven 3.0.3 (see [1]).

Best, Fabian

>>
>> 5. I thought it might be a classpath issue (since my laptop doesn't have

>>
>> 6.  I realized this wasn't necessarily doing anything to the resolution

>>
>>
>> this.userCodeClassLoader = JobWithJars.buildUserCodeClassLoader(getAllLibraries(),

>>
>>
>>
>> getAllLibraries() does seem to set the jar that you pass into the `flink`
>> command at the top of the class resolution hierarchy, which, as my previous
