Josh Elser resolved HBASE-23265.
--------------------------------
    Resolution: Won't Fix

HBase 1.1 is marked as end-of-maintenance and not receiving more fixes. Same 
goes for HBase 1.2.

If you can validate that this is also a problem on a current HBase 1.x release, 
I would assume that we'd be interested in fixing it.

>                 Key: HBASE-23265
>                 URL: https://issues.apache.org/jira/browse/HBASE-23265
>             Project: HBase
>          Issue Type: Improvement
>          Components: Coprocessors
>    Affects Versions: 1.1.2
>            Reporter: Ondrej Kvasnicka
>            Priority: Minor
>
> According to our observation, a running coprocessor that is automatically 
> stopped prior to region split will not be automatically restarted for the 
> region that was about to be split in case the split attempt is rolled back.
> The expected behavior would be for the coprocessor to be automatically 
> restarted in such situation.
> According to [this 
> conversation|https://lists.apache.org/thread.html/9f83d32c50e0f9b05fff183897f5a3ccdb3c2e94b0e9d1a0f9064646@%3Cuser.hbase.apache.org%3E]
>  the lack of the automatic restart looks more like an omission rather than an 
> intended behavior.
> A possible work-around seems to be handling the restart explicitly in 
> RegionObserver#postRollBackSplit() implementation, such as in [this 
> example|https://github.com/splicemachine/spliceengine/blob/aa9d66e3d33ea04d67203eb86b3e6e3ba768e267/hbase_pipeline/src/main/java/com/splicemachine/derby/hbase/SpliceIndexObserver.java#L206].
