Fabian Hueske commented on FLINK-5227:
--------------------------------------

I think adding {{flink-table}} to {{flink-dist}} should be a different issue.

We do not want to bundle {{flink-table}} into the main jar file. This jar file 
should only contain the what is absolutely needed. The {{./opt}} folder 
contains jar files that can be moved to {{./lib}} to include the dependencies 
when the TMs are started.

>          Issue Type: Improvement
>          Components: Documentation, Table API & SQL
>    Affects Versions: 1.2.0, 1.1.3

> {{flink-table}} depends on Apache Calcite which includes a JDBC Driver that 
> prevents classloaders from being collected. This is a known issue with 
> {{java.sqlDriverManager}} and can eventually cause OOME Permgen Taskmanager 
> failures.
> The current workaround is to not include {{flink-table}} in the fat job JAR. 
> Instead the {{flink-table}} jar files should be added to the {{lib}} folder 
> of the TaskManagers.
