Vineet Garg commented on HIVE-20561: ------------------------------------ [~bslim] According to Kafka doc [LINK|https://kafka.apache.org/10/javadoc/index.html?org/apache/kafka/clients/consumer/KafkaConsumer.html] position returns the offset of the next record to be fetched, so how is it different from what we used to do previously? > Use the position of the Kafka Consumer to track progress instead of Consumer > Records offsets > -------------------------------------------------------------------------------------------- > > Key: HIVE-20561 > URL: https://issues.apache.org/jira/browse/HIVE-20561 > Project: Hive > Issue Type: Bug > Affects Versions: 4.0.0 > Reporter: slim bouguerra > Assignee: slim bouguerra > Priority: Major > Fix For: 4.0.0 > > Attachments: HIVE-20561.2.patch, HIVE-20561.3.patch, HIVE-20561.patch > > > Kafka Partitions with transactional messages (post 0.11) will include commit > or abort markers which indicate the result of a transaction. The markers are > not returned to applications, yet have an offset in the log. Therefore the > end of Stream position can be the offset of a control message. > This Patch change the way how we keep track of the consumer position by using > {code} consumer.position(topicP) {code} as oppose to using the offset of the > consumed messages. > Also I have done some refactoring to help code readability hopefully. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
