James Clampffer commented on HDFS-9118:
---------------------------------------
Shouldn't getting the stack address of a local variable boil down (at least on
x86) to just reading whats in ESP-a constant offset? That should be doable in
a few cycles, superscalar complications aside, unless I'm missing something.
Either way good idea on allowing things to opt-in based on logging levels.
I'll add that.

> URL: https://issues.apache.org/jira/browse/HDFS-9118
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs-client
> Affects Versions: HDFS-8707
> Reporter: Bob Hansen
> Assignee: James Clampffer
>
> 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
