   Thanks, @prakharchaube - good idea! The code to handle job failures is kind 
of boilerplate for all Nutch tools. But there's some variation regarding the 
cleanup. In addition, log messages and stack traces should show the originating 
class (Injector, etc.) and not that of a utility class.
   
   > What about 
[StringUtil.java](https://github.com/apache/nutch/blob/master/src/java/org/apache/nutch/util/StringUtil.java)
   
   Maybe 
[NutchJob](https://github.com/apache/nutch/blob/master/src/java/org/apache/nutch/util/NutchJob.java)
 is also a good location for code for shared by Nutch tools/jobs.

> In Job classes in case job doesn't succeed a failure message is initialized 
> as follows:
> _String message = "Generator job did not succeed, job status:"_
>               _+ job.getStatus().getState() + ", reason: "_
>               _+ job.getStatus().getFailureInfo();_
> However, this message doesn't contain JobId which can make it really hard to 
> reach the exact job from the logs. Adding JodId to this message will make it 
> easier to track and locate for debugging.
