-----------------------------------------
Summary: netty 3 file for Spark integration contains LGPL license
Key: TINKERPOP3-719
URL: https://issues.apache.org/jira/browse/TINKERPOP3-719
Project: TinkerPop 3
Issue Type: Bug
Components: build-release
Environment: all
Reporter: David Robinson
Assignee: stephen mallette
The netty-3x jar contains an LGPL license as follows:
./hadoop-gremlin/target/hadoop-gremlin-3.0.0-SNAPSHOT-standalone/lib/netty-3.5.13.Final.jar
grep LICENSE.jboss-logging.txt netty-3.5.13.Final.jar
Looking at LICENSE.jboss-logging.txt, it shows this:
GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
etc.
Unfortunately, netty 3 is a dependency because of Spark / Akka.
I am currently working with the Spark / Akka community to attempt to fix the
problem on their end (Spark currently has this same GPL license due to Akka) so
that we can fix the problem on our end. Opening this as a reminder for us.
Tried netty 4, which solves the LGPL problem, but it is incompatible with the
version of Spark supported by TinkerPop - and Spark/Akka doesn't support netty
4 yet to my knowledge.
