Chaitanya created APEXMALHAR-2158: ------------------------------------- Summary: Duplication of data emitted when the Kafka Input Operator(0.8 version) redeploys Key: APEXMALHAR-2158 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2158 Project: Apache Apex Malhar Issue Type: Bug Reporter: Chaitanya Assignee: Chaitanya
Kafka Input Operator failure recovery depends on offsetStats map. "offsetStats" map is updated whenever the message is emitted from operator. When the operator goes down and comes back, operator sets this map to the consumer and start reading from these offsets. Consumer reads the last emitted message again and operator emits it. Solution: Increment the offsets before setting to the consumer. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
