James Clampffer updated HDFS-9699:
----------------------------------
Attachment: cancel_backtrace.txt
asio throwing a std::system error during cancellation that ends up terminating
the process in the attached backtrace
> libhdfs++: Add appropriate catch blocks for ASIO operations that throw
> ----------------------------------------------------------------------

>
> libhdfs++ doesn't create exceptions of its own but it should be able to
> gracefully handle exceptions thrown by libraries it uses, particularly asio.
> libhdfs++ should be able to catch most exceptions within reason either at the
> call site or in the code that spins up asio worker threads. Certain system
> exceptions like std::bad_alloc don't need to be caught because by that point
> the process is likely in a unrecoverable state.
