James Taylor commented on OMID-103:
-----------------------------------

We add FirstKeyOnlyFilter if the schema only has row key columns (or if it only 
references columns in the primary key). The code is in 
BaseResultIterators.initializeScan().

> DeleteFamily marker still visible after rollback fails

>                 Key: OMID-103
>                 URL: https://issues.apache.org/jira/browse/OMID-103
>             Project: Apache Omid
>          Issue Type: Bug
>            Reporter: James Taylor
>            Priority: Major
>
> If a DeleteFamily marker is written to HBase and the subsequent abort of the 
> transaction fails, the delete marker is still visible and mistakenly 
> continues to take effect. For a repro, see 
> TransactionIT.testFailureToRollbackAfterDelete() which passes for Tephra but 
> fails for Omid.
