[jira] [Commented] (STORM-1622) Topology jars referring to shaded classes of older version of storm jar cannot be run in Storm 1.0.0

["Abhishek Agarwal (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STORM-1622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15193267#comment-15193267 ] 

Abhishek Agarwal commented on STORM-1622:
-----------------------------------------

Got this exception while submitting the topology built with 0.9.6 on Storm 1.0.0 cluster
java.lang.NoClassDefFoundError: org/apache/storm/guava/base/Preconditions

[~revans2] what do you think of this? It can be fixed in 1.0.0 using the ClientJarTransformer with trivial changes. I am not sure how it will work for 0.10.0 though.

> changes the package names of shaded classes inside the storm.  These classes are shipped inside the maven release of storm-core jar and can depended upon the topology jar. Jar built with older version of storm-core and using this dependency, wouldn't run on newer version of storm cluster.
