Hitesh Kapoor commented on APEXMALHAR-2239:
-------------------------------------------
[~d9liang] you are getting this error because column 'STARTDATE1' is not
present in the table and you are trying to access it.
[~venkateshkkothapalli] I had a look at the code and tried few scenarios and I
don't think you will get the stack trace as mentioned in the description if
(only) field names do not match in POJO and table. However after a code walk
through I was able to get the mentioned stack trace if we set a query to fetch
rows and have additional columns in fieldInfos.
I will be attaching the code changes for testJdbcPojoInputOperator() in
JdbcPojoOperatorTest.java to get a repro of the mentioned scenario.
[~venkateshkkothapalli] please confirm if this is the required scenario so that
[~d9liang] can proceed further if not please give us a repro scenario or some
additional details so that we can try to re create it.
