Summary: JdbcPOJOPollInputOperator fails with NullPointerException when PostgreSQL driver Key: APEXMALHAR-2330 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2330 Project: Apache Apex Malhar Issue Type: Bug Reporter: Deepak Narkhede Assignee: Deepak Narkhede Here is the description: Problem: JdbcPOJOPollInputOperator fails with NullPointerException when PostgreSQL driver. Problem Description: 1) When JdbcPOJOPollInputOperator tries to populateColumnDataTypes, column names retrieved from resultmetadata from database ( this case : Postgres) are all lowercase. 2) Whereas columnDatatypes specified in fieldinfos might be in same case. 3) Internally hashmap ( nameToType) is used which mismatches if column name and fieldinfo are not in same case. Hence columnDataTypes is empty which causes null exception in activate call. Proposed Solution: Using similar case for hashmap and column names irrespective of any database used for JdbcPOJOPollInputOperator. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
