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.
