Bob Hansen commented on HDFS-9117:
----------------------------------
bq. Unfortunately requiring c++ exceptions might not be an option for other
users as discussed in the libhdfs3 branch.
I'm sorry; I didn't see that discussion in libhdfs3. Can you link to it or
summarize it here? Have things changed since your comment on this Jira on
10/27:
bq. 2. The code should not use C++ exceptions.
Re; Optional

I'm okay to bring it in. Some example can be:
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Support/ErrorOr.h
http://www.boost.org/doc/libs/1_59_0/boost/optional/optional.hpp

Are you suggesting copying one of those implementations into our codebase? We
can, but it seems a pretty heavyweight solution. I hate to ask, but should
that be a distinct Jira for bringing in third party code?

> For environmental compatability with HDFS installations, libhdfs++ should be
> able to read the configurations from Hadoop XML files and behave in line with
> the Java implementation.
> Most notably, machine names and ports should be readable from Hadoop XML
> configuration files.
> Similarly, an internal Options architecture for libhdfs++ should be developed
> to efficiently transport the configuration information within the system.
