------------------------------------
Summary: Add warning to include flink-table in job fat jars
Key: FLINK-5227
URL: https://issues.apache.org/jira/browse/FLINK-5227
Project: Flink
Issue Type: Improvement
Components: Documentation, Table API & SQL
Affects Versions: 1.1.3, 1.2.0
Reporter: Fabian Hueske
Fix For: 1.2.0, 1.1.4
{{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.
