ayache khettar updated HBASE-11875:
-----------------------------------
    Description: 
Hi

HbaseZeroCopyByteString class isn't accessible in OSGI based environment. The 
reason is that it ends up in a separate route package within an OSGI bundle. As 
such the class isn't viewable by the classLoader.

I understand that the hbase-module isn't an osgi bundle, but there is another 
project which makes use of this module to generate an osgi bundle for the OSGI 
container: 
https://github.com/apache/servicemix4-bundles/tree/trunk/hbase-0.98.0-hadoop2. 
If you get hold of the binary or source artefact from maven, unzip the jar and 
you will see the structure of the project:
com/google/ (classes defined in this package are not visible by the 
classLoader).
org/apache/hbase

I understand the reason of having a foreign package cause goggle base class 
defines package level methods. It would be nice to work out another way of 
extending google protobuf classes. I would recommend going for composition as 
opposed to inheritance that will solve the problem.

Regards,

Ayache
