-----------------------------------------
Summary: Shade plugin copies signature files from original jar
into fat jar
Key: FLINK-2607
URL: https://issues.apache.org/jira/browse/FLINK-2607
Project: Flink
Issue Type: Bug
Components: Quickstarts
Affects Versions: 0.9, 0.10
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: 0.10
The Quickstart project contains a Maven configuration that builds a fat jar
using the Maven Shade plugin. It copies the {{META-INF}} folder of the original
jar into the fat jar as well. That can lead to a {{SecurityException}} when
submitting jobs to the cluster because the signature file contained in the
original jar is not suitable for the fat jar.
{noformat}
java.lang.SecurityException: Invalid signature file digest for Manifest main
attributes
{noformat}
The solution is to change the configuration of the Shade plugin to ignore the
signature files in the {{META-INF}} folder when copying the dependencies to the
fat jar.
