    Ok, so it seems like Java serialization of the Kinesis classes was removed 
only starting from 1.3.x.
    That means unless we do some classloading trick, we can't really upgrade 
the Kinesis consumer dependencies until 1.2 savepoint compatibility is no 
longer supported.


> Upgrade kinesis producer library, kinesis client library, and AWS SDK in 
> flink-connector-kinesis

>          Issue Type: Bug
>          Components: Kinesis Connector
>    Affects Versions: 1.3.2
>            Reporter: Bowen Li

> We need to upgrade KPL and KCL to pick up the enhanced performance and 
> stability for Flink to work better  with Kinesis. Upgrading KPL is specially 
> necessary, because the KPL version Flink uses is old, and doesn't have good 
> retry and error handling logic.
> *KPL:*
> flink-connector-kinesis currently uses kinesis-producer-library 0.10.2, which 
> is released in Nov 2015 by AWS. It's old. It's the fourth release, and thus 
> problematic. It doesn't even have good retry logic, therefore Flink fails 
> really frequently (about every 10 mins as we observed) when Flink writes too 
> fast to Kinesis and receives RateLimitExceededException, 
> Quotes from https://github.com/awslabs/amazon-kinesis-producer/issues/56, 
> "*With the newer version of the KPL it uses the AWS C++ SDK which should 
> offer additional retries.*" on Oct 2016. 0.12.5, the version we are upgrading 
> to, is released in May 2017 and should have the enhanced retry logic.
> *KCL:*
> Upgrade KCL from 1.6.2 to 1.8.1
> *AWS SDK*
> from 1.10.71 to 1.11.171
