Colin Patrick McCabe commented on HADOOP-10443:
-----------------------------------------------
Implemented this via visibility pragmas in libhdfs.h
> limit symbol visibility in libhdfs-core.so and libyarn-core.so

> Key: HADOOP-10443
> URL: https://issues.apache.org/jira/browse/HADOOP-10443
> Project: Hadoop Common
> Issue Type: Sub-task
> Reporter: Colin Patrick McCabe
> Priority: Minor
> Fix For: HADOOP-10388
>
>
> We should avoid exposing all the symbols of libhdfs-core.so and
> libyarn-core.so. Otherwise, we they conflict with symbols used in the
> applications using the libraries. This can be done with gcc's symbol
> visibility directives.
> Also, we should probably include libuv and libprotobuf-c statically into our
> libraries, since most distributions don't yet include these libraries, and we
> don't want to have version issues there.
