--------------------------------------------
[~Hitesh_]I do need some help. I'm not sure if the following will reproduce the
problem. I tried to change the column name
in JdbcPojoOperatorTest.java
from STARTDATE to STARTDATE1
fieldInfos.add(new FieldInfo("STARTDATE1", "startDate1", null));
It gives a different error though:
java.lang.RuntimeException: java.sql.SQLSyntaxErrorException: user lacks
privilege or object not found: STARTDATE1
