Bob Hansen commented on HDFS-9627:
----------------------------------
Additional minor comment: for consistency, we should mark the methods as
{{LIBHDFS_EXTERNAL}}, which means including {{hdfs.h}}, which means we need to
disambiguate the C {{hdfs.h}} from the libdhfdspp {{hdfs.h}} (which declares
FileSystem and FileHandle). Perhaps renaming this patch's {{hdfspp.h}} to
{{hdfs_ext.h}} and renaming {{libhdfs/include/libhdfspp/hdfs.h}} to
{{hdfspp.h}} is a good set of names?
Nothing is ever simple.

> Libhdfs doesn't have this but libhdfs3 has a "hdfsGetLastErrorString"
> function. The C API needs to be able to pass out error messages that are
> more specific than what errno can provide.
> This functionality should be exposed via a new public header in order to keep
> hdfs.h consistent with the libhdfs header.
