------------------------------
Summary: Sqoop2: Add a NullMatcher
Key: SQOOP-1987
URL: https://issues.apache.org/jira/browse/SQOOP-1987
Project: Sqoop
Issue Type: Sub-task
Reporter: Qian Xu
Assignee: Qian Xu
The {{MatcherFactory}} will create different matcher according to toSchema and
fromSchema conditions.
In {{LocationMatcher}}, it has a rule 0
{code}
public Object[] getMatchingData(Object[] fields) {
if (getToSchema().isEmpty()) {
// No destination schema found. No need to convert anything.
return fields;
}
{code}
I'm thinking we can create a third matcher {{NullMatcher}}, which simply return
input fields as result.
