Subject [jira] [Commented] (HDFS-9118) Add logging system for libdhfs++
Date Mon, 21 Sep 2015 23:40:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14901630#comment-14901630
] 

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.

> 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
