--------------------------------
Code Review: http://gerrit.cloudera.org:8080/24862
> Fix protobuf symbol hiding logic for kudu client to work with LLD/Mold
> ----------------------------------------------------------------------
>
> Key: KUDU-3614
> URL: https://issues.apache.org/jira/browse/KUDU-3614
> Project: Kudu
> Issue Type: Bug
> Components: build, client
> Affects Versions: 1.17.0
> Reporter: Joe McDonnell
> Assignee: Alexey Serbin
> Priority: Major
>
> In KUDU-3334, we started hiding libprotobuf symbols in kudu client to avoid
> conflicts with Impala. LLD and Mold use a slightly different semantic for
> --exclude-libs and it won't work unless we also add the ".a" extension.
> Impala had an issue like that when we started supporting Mold (see the fix in
> IMPALA-12807 here:
> [https://github.com/apache/impala/commit/88dcdfd4662d0ec4a6e0d81d643d207f6e5ed900]
> ).
> The fix is to add the ".a" extension (which also works on gold).
> This only comes up if Impala builds Kudu with Clang/LLD, which we currently
> never do. I only found this through experimentation.
