------------------------------
Summary: Sqoop2: isNull handling should be moved to
CSVIntermediateDataFormat
Key: SQOOP-1988
URL: https://issues.apache.org/jira/browse/SQOOP-1988
Project: Sqoop
Issue Type: Sub-task
Reporter: Qian Xu
Assignee: Qian Xu
Matcher should only match fields, not do any value modification (except when
fallback to null ), Given argument {{fields}} should have converted null
values.
Currently it will convert {{null}} {{"NULL"}} {{"null"}} {{"'null'"}} and
{{""}} to null. They are CSV relevant. As we do not have a knowledge of what
intermediate data format is used, I'd remove the check and convert here.
Another benefit is performance gain. Thanks [~jerrychenhf]
