[Bug][Manager] When creating KafkaSource, the autoOffsetReset param cannot be empty

[LiJie20190102]

What happened

When I used the client to create a data synchronization task for Kafka2Hive I found that the Kafka source must be set to 'autoOffsetReset' when submitting it, and an exception occurred at this time

What you expected to happen

If I have not set 'autoOffsetReset', there should be a default value so that no errors will be reported

How to reproduce

Executing the ‘org.apache.inlong.manager.client.ut.Kafka2HiveTest#testCreateGroupForHive’ method will result in an exception

Environment

No response

InLong version

1.9.0

InLong Component

InLong Manager
