Description
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 (https://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.
