Enis Soztutar commented on HBASE-13576:
---------------------------------------
LGTM except that we should re-throw the exception from the first region (if
possible) so that we do not lose the exception context if limit is configured
as 0.
> HBCK enhancement: Failure in checking one region should not fail the entire
> HBCK operation.

> HBaseFsck#checkRegionConsistency() checks region consistency and repair the
> corruption if requested. However, this function expects some exceptions.
> For example, in one aspect of region repair, it calls
> HBaseFsckRepair#waitUntilAssigned(), if a region is in transition for over
> 120 seconds (default value of "hbase.hbck.assign.timeout" configuration),
> IOException would throw.
> The problem is that one exception in checkRegionConsistency() would kill
> entire hbck operation, because the exception would propagate up.
> The proposal is that if the region is not META region ( or a system table
> region if we prefer), we can skip the region if
> HBaseFsck#checkRegionConsistency() fails. We could print out skip regions in
> summary section so that users know to either re-run or investigate potential
> issue for that region.
