> Project: Tajo
> Issue Type: Improvement
> Components: storage
> Affects Versions: 0.9.0
> Reporter: Jongyoung Park

> Fix For: 0.10

>
> As I investigated, many appenders have possibility to cause NPE such as
> TAJO-1227.
> It seems checking null for each variables is ineffective.
> Fortunately, FileAppender supports a state variable named 'inited'.
> If it is used commonly, things like NPE could be avoided.
