>             Project: Kudu
>          Issue Type: Improvement
>          Components: spark
>    Affects Versions: 1.7.1
>            Reporter: Will Berkeley
>            Priority: Major

> If a user tries to delete a row from a Kudu table using kudu-spark but the row is not present, they receive an exception like
> {{java.lang.RuntimeException: failed to write N rows from DataFrame to Kudu; sample errors: Not found: key not found (error 0)}}
> This is the expected behavior, but it might also be nice to allow users to ignore PK errors so they can achieve clean semantics of "delete if present, else ignore".
