>                 URL: https://issues.apache.org/jira/browse/HIVE-3449
>             Project: Hive
>          Issue Type: Improvement
>          Components: Build Infrastructure
>    Affects Versions: 0.9.0
>            Reporter: Swarnim Kulkarni
>
> Given that the hive build is an enormously loooong build (~ 6hrs), it might 
> be very helpful if there are some checkpointing capabilities available to be 
> able to resume a build from  failed point and not have to restart everything 
> on a single test failure.
> One possible way to do this would be to use the ant uptodate task to check 
> set of target files to be more up-to-date than given set of source files and 
> execute a target only if that is true. 
> By default this capability could be off but can be activated with the 
> -Dresume=true argument.
