James Clampffer commented on HDFS-9827:
---------------------------------------
Superset of the work HDFS-9699. Depending on how granular we want the patch to
be I can close that one.
> libhfds++: C++ exceptions should never escape the C API
> -------------------------------------------------------
>
> Key: HDFS-9827
> URL: https://issues.apache.org/jira/browse/HDFS-9827
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs-client
> Reporter: Bob Hansen
>
> Some low-level subsystems (asio, rapidxml) throw exceptions on error. While
> our internal code doesn't utilize exceptions, these are part of the libraries
> we are using.
> Calls to asio should be wrapped in try blocks.
> For additional safety, all of the C api implementations should have
> try...catch(...) blocks to catch any C++ exceptions and make sure they don't
> bring down the calling stack, which might have no concept of exceptions.
