Re: storm.backtype error

[Xin Wang <da...@gmail.com>]

hi Daniela,

In the latest 1.0.0 version, the class packages have been changed from
"backtype.storm" to "org.apache.storm" so the topology code compiled with
older version won't run on the Storm 1.0.0 just like that. Backward
compatibility is available through following configuration

`client.jartransformer.class: "org.apache.storm.hack.StormShadeTransformer"`

You need to add the above config in storm installation if you want to run
the code compiled with older versions of storm. The config should be added
in the machine you use to submit your topologies.

Refer to https://issues.apache.org/jira/browse/STORM-1202 for more details.
