Krystian Nowak created STORM-355:
------------------------------------
Summary: Duplicated netty dependency in lib classpath
Key: STORM-355
URL: https://issues.apache.org/jira/browse/STORM-355
Project: Apache Storm (Incubating)
Issue Type: Bug
Affects Versions: 0.9.2-incubating
Reporter: Krystian Nowak
Both _netty_ dependencies - [_3.2.2.Final_ (from
_org.jboss.netty_)|http://search.maven.org/#artifactdetails|org.jboss.netty|netty|3.2.2.Final|bundle]
and [_3.6.3.Final_ (from
_io.netty_)|http://search.maven.org/#artifactdetails|io.netty|netty|3.6.3.Final|bundle]
- are found in _lib_ folder:
{noformat}
knowak@knowak-dell:~/incubator-storm-0.9.2-incubating/storm-dist/binary/target/apache-storm-0.9.2-incubating/lib$
ls -al | grep netty
-rw-rw-r-- 1 knowak knowak 785556 Jun 17 12:38 netty-3.2.2.Final.jar
-rw-rw-r-- 1 knowak knowak 1202373 Jan 27 11:14 netty-3.6.3.Final.jar
{noformat}
as both of them are configured in _pom.xml_:
{noformat}
knowak@knowak-dell:~/incubator-storm-0.9.2-incubating/storm-core$ mvn
dependency:list | grep netty
[INFO] io.netty:netty:jar:3.6.3.Final:compile
[INFO] org.jboss.netty:netty:jar:3.2.2.Final:compile
{noformat}
and it seems that the older one is transitively brought by [_zookeeper_
dependency|http://search.maven.org/remotecontent?filepath=org/apache/zookeeper/zookeeper/3.4.5/zookeeper-3.4.5.pom]:
{noformat}
knowak@knowak-dell:~/incubator-storm-0.9.2-incubating/storm-core$ mvn
dependency:tree
...
[INFO] +- org.apache.curator:curator-framework:jar:2.4.0:compile
[INFO] | +- org.apache.curator:curator-client:jar:2.4.0:compile
[INFO] | \- org.apache.zookeeper:zookeeper:jar:3.4.5:compile
[INFO] | +- jline:jline:jar:2.11:compile
[INFO] | \- org.jboss.netty:netty:jar:3.2.2.Final:compile
...
[INFO] +- io.netty:netty:jar:3.6.3.Final:compile
...
{noformat}
so possibly [_curator-framework_ dependency
section|https://github.com/apache/incubator-storm/blob/master/pom.xml#L349]
needs adding an exclusion of _org.jboss.netty_:_netty_
