James Clampffer updated HDFS-9118:
----------------------------------
Attachment: HDFS-9118.HDFS-8707.003.patch
New patch, incorporates a lot of [~bobhansen]'s suggestions.
-rebased onto head
-log macros to avoid creating LogMessage objects if they won't be logged
-add a separate public header for the C logging data structures and defines so
that the implementation doesn't have to drag in the whole public API
-get rid of lock macros
-more helpful output when null pointers are passed to operator<<(const char*)
and operator<<(std::string*)
-remove some garbage that slipped into the last patch (stuff commented out but
not deleted)

> With HDFS-9505, we've starting logging data from libhdfs++. Consumers of the
> library are going to have their own logging infrastructure that we're going
> to want to provide data to.
> libhdfs++ should have a logging library that:
> * Is overridable and can provide sufficient information to work well with
> common C++ logging frameworks
> * Has a rational default implementation
> * Is performant
