Fabian Hueske created FLINK-5227: ------------------------------------ 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
