Stefania commented on CASSANDRA-11474:
--------------------------------------
We should also make sure that if a child process aborts during startup, then
the error message is displayed to the user. At the moment the only way to see
exceptions thrown by worker processes during startup is via {{--debug}}.
> cqlsh: COPY FROM should use regular inserts for single statement batches

> URL: https://issues.apache.org/jira/browse/CASSANDRA-11474
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Reporter: Stefania

> Fix For: 2.2.x, 3.0.x, 3.x

>
> I haven't reproduced it with a test yet but, from code inspection, if CQL
> rows are larger than {{batch_size_fail_threshold_in_kb}} and this parameter
> cannot be changed, then data import will fail.
> Users can control the batch size by setting MAXBATCHSIZE.
> If a batch contains a single statement, there is no need to use a batch and
> we should use normal inserts instead or, alternatively, we should skip the
> batch size check for unlogged batches with only one statement.
