>                 Key: HBASE-10842
>                 URL: https://issues.apache.org/jira/browse/HBASE-10842
>             Project: HBase
>          Issue Type: Improvement
>    Affects Versions: 0.98.1, 0.96.1.1
>            Reporter: Richard Ding
>            Assignee: Richard Ding
>            Priority: Minor

> In a few of source files, the logger is defined as 
> {code}
> private final Log LOG = LogFactory.getLog(MyClass.class);
> {code}
> This should be changed to static final.
> One question is about the following declaration:
> {code}
> private final Log LOG = LogFactory.getLog(this.getClass());
> {code}
> In this form, the logger can be shared by derived classes. But one will get NPE when
logging in methods that are invoked inside the constructors.
