--------------------------------------
Summary: Referencing external package com/google/protobuf/ inside
hbase-protcol module won't work in OSGI environment
Key: HBASE-11875
URL: https://issues.apache.org/jira/browse/HBASE-11875
Project: HBase
Issue Type: Improvement
Components: Protobufs
Affects Versions: 0.98.6
Environment: OSGI container
Reporter: ayache khettar
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.
Regards,
Ayache
