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. > Null pointer exception in JDBCPojoInputOperator when the field names do not > match in Pojo, table > ------------------------------------------------------------------------------------------------ > > Key: APEXMALHAR-2239 > URL: https://issues.apache.org/jira/browse/APEXMALHAR-2239 > Project: Apache Apex Malhar > Issue Type: Bug > Affects Versions: 3.5.0 > Reporter: Venkatesh Kottapalli > Assignee: Dongming Liang > Priority: Minor > > The following exception is thrown in JDBCPojoInputOperator when the field > names for the table provided in the FieldInfo mapping don't match with the > column names of the table. > Exception: > Abandoning deployment due to setup failure. java.lang.NullPointerException > at > com.datatorrent.lib.db.jdbc.JdbcPOJOInputOperator.activate(JdbcPOJOInputOperator.java:366) > at > com.datatorrent.lib.db.jdbc.JdbcPOJOInputOperator.activate(JdbcPOJOInputOperator.java:67) > at com.datatorrent.stram.engine.Node.activate(Node.java:619) > at > com.datatorrent.stram.engine.StreamingContainer.setupNode(StreamingContainer.java:1336) > at > com.datatorrent.stram.engine.StreamingContainer.access$100(StreamingContainer.java:130) > at > com.datatorrent.stram.engine.StreamingContainer$2.run(StreamingContainer.java:1388) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
