----------------------------------------
Resolution: Incomplete
> Mechanism for atomic recovery from partial failure when atomically
> bulk-loading multi-CF rows.
> ----------------------------------------------------------------------------------------------

> Key: HBASE-4652
> URL: https://issues.apache.org/jira/browse/HBASE-4652
> Project: HBase
> Issue Type: Bug
> Reporter: Jonathan Hsieh
> Priority: Major
>
> The suggestions from HBASE-4552 and initial implementations could violate row
> atomicity if there is a failure while bulk-loading multiple CF rows. A
> mechanism to atomically rollback or commit only upon completion (mvcc at the
> store level) is needed if a partial failures encountered when attempting to
> bulk load multiple families.
> For example, let's say I want to bulk load a region with cfs A, B, C. I issue
> a call to an RS region to atomically bulkload the HFiles. The RS loads A and
> B successfully but fails on C (hdfs failure, or rs goes down, etc). We could
> rollback A and B - if we don't we would have A and B loaded but not C and
> have an atomicity violation.
