Andrew Purtell commented on HBASE-11118:
----------------------------------------

How do we sync our use of google's protoc in the compile-protobuf build target 
with an alternative runtime? I'm not familiar with protostuff. Does it have 
it's own compiler ?

> I am running into the problem described in 
> https://issues.apache.org/jira/browse/HBASE-10304, while trying to use a 
> newer version within cascading.hbase 
> (https://github.com/cascading/cascading.hbase).
> One of the features of cascading.hbase is that you can use it from lingual 
> (http://www.cascading.org/projects/lingual/), our SQL layer for hadoop. 
> lingual has a notion of providers, which are fat jars that we pull down 
> dynamically at runtime. Those jars give users the ability to talk to any 
> system or format from SQL. They are added to the classpath  programmatically 
> before we submit jobs to a hadoop cluster.
> Since lingual does not know upfront , which providers are going to be used in 
> a given run, the HADOOP_CLASSPATH trick proposed in the JIRA above is really 
> clunky and breaks the ease of use we had before. No other provider requires 
> this right now.
> It would be great to have a programmatical way to fix this, when using fat 
> jars.
