HBASE-related dependencies upgrade #51
Description
In #42 I faced a dependency hell. Different components uses different versions of protobuf, hadoop-* and other libraries. It makes it almost impossible to update dependencies.
In my cases first thing to break were a HBASE tests. And It seems that we can solve this issue by updating HBASE plugin to use shaded versions of libraries: hbase-shaded-client. And its dependencies (e.g. hbase-shaded-protobuf). It is expected that it will use own namespace for dependencies (e.g. com.google.protobuf.ByteString -> org.apache.hadoop.hbase.shaded.com.google.protobuf.ByteString) and this should solve dependencies issues.
Overall:
- build a PoC with shaded version of
hbase-client - estimate PXF bundle size increase (and provide recomendations on how to build PXF without HBASE support)
