> Key: HBASE-13759
> URL: https://issues.apache.org/jira/browse/HBASE-13759
> Project: HBase
> Issue Type: Sub-task
> Components: proc-v2
> Affects Versions: 2.0.0, 1.2.0
> Reporter: Matteo Bertozzi
> Assignee: Matteo Bertozzi
> Priority: Trivial
> Fix For: 2.0.0, 1.2.0
>
> Attachments: HBASE-13759-v0.patch, HBASE-13759-v1.patch
>
>
> Adds the ability to yield the procedure every execution step.
> by default, a procedure will try to go begin to end without stopping.
> This allows procedures to be nice to other procedures.
> one usage example is ServerShutdownHandler where we want everyone to make
> some progress.
> Allows procedure to throw InterruptedException, the default handling will be:
> "ask the master if there is an abort of stop. If there is, stop executions
> and exit. Else, clear the IE and carryon executing. the interruted procedure
> will retry".
> If the procedure implementor wants a different behavior, the IE can be
> catched and custom handling can be performed.
