----------------------------
Parent: KUDU-422
> Master should handle the case where we REPLICATE fails
> ------------------------------------------------------
>
> Key: KUDU-495
> URL: https://issues.apache.org/jira/browse/KUDU-495
> Project: Kudu
> Issue Type: Sub-task
> Components: master
> Affects Versions: M5
> Reporter: Alex Feinberg
> Assignee: Alex Feinberg
>
> Master should handle the case where the REPLICATE fails (which I discovered
> when running a transaction against a non-leader case) in SysTables.
> This is a bit tricky as for master we update the in-memory tables *first*,
> then commit the transaction.
> Only way would be able to do the following:
> Under the lock for the appropriate CopyOnWrite object--
> 1) Save the old version of the object.
> 2) Make the appropriate modification.
> 3) If REPLICATE fails, go back to the old version.
