Haohui Mai commented on HDFS-9118:
----------------------------------
The interfaces of logging class are quite closed to the one used in snappy and
glog. A rational choice is to make it an abstract class and allow users to
specify the instance in the {{Options}} instance.
> Add logging system for libdhfs++

> Key: HDFS-9118
> 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
>
> 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
