John Bodley commented on AIRFLOW-259:
-------------------------------------
[~jackjack10] I'm unsure as we're currently not using either of these
operators.
> MySqlToHiveOperator incorrectly requotes strings due to csv.writer
> configuration

> Key: AIRFLOW-259
> URL: https://issues.apache.org/jira/browse/AIRFLOW-259
> Project: Apache Airflow
> Issue Type: Bug
> Components: operators
> Reporter: John Bodley
> Priority: Minor
>
> The MySqlToHiveOperator has the same issue as the HiveToMySqlOperator when
> bulk_load=True, i.e. the both use a csv.writer as an intermediate step, which
> mangles strings containing quotes due to the quoting logic.
> For example a JSON blob in MySQL of the form
> {"dashboard_id": "85"}
> becomes
> "{""dashboard_id"": 85}"
> in Hive.
