-----------------------------------

             Summary: non environment variable solution for "IllegalAccessError: class com.google.protobuf.ZeroCopyLiteralByteString
cannot access its superclass com.google.protobuf.LiteralByteString"
                 Key: HBASE-11118
                 URL: https://issues.apache.org/jira/browse/HBASE-11118
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.98.2
            Reporter: André Kelpe


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.
