Swapnil Ghike updated KAFKA-495: -------------------------------- Attachment: kafka-495-v0.8-v2.patch - After discussing with Jun, inserted topic validation in createTopic() instead of LogManager in 0.8. - Created a singleton Topic in Utils/Topic.scala, topicNameValidators in KafkaConfig and CreateTopicCommand default to the maxNameLen in this singleton. The value at both these locations can be overridden. - The check in LogManager.createLog is not necessary anymore because the topic would be validated by then, removed this check. - Added a new unit test in test/utils for topic validation. - Tested this change with bin/kafka-create-topic.sh for fun. - Opened KAKFA-505 to deal with the TopicMetaDataResponse errorcode. > Handle topic names with "/" on Kafka server > ------------------------------------------- > > Key: KAFKA-495 > URL: https://issues.apache.org/jira/browse/KAFKA-495 > Project: Kafka > Issue Type: Bug > Affects Versions: 0.7, 0.8 > Reporter: Neha Narkhede > Assignee: Swapnil Ghike > Labels: bugs > Fix For: 0.8, 0.7.1 > > Attachments: kafka-495-v0.8.patch, kafka-495-v0.8-v2.patch, > kafka-495-v1.patch, kafka-495-v2.patch, kafka-495-v3.patch, kafka-495-v4.patch > > > If a producer publishes data to topic "foo/foo", the Kafka server ends up > creating an invalid directory structure on the server. This corrupts the > zookeeper data structure for the topic - /brokers/topics/foo/foo. This leads > to rebalancing failures on the consumer as well as errors on the zookeeper > based producer. > We need to harden the invalid topic handling on the Kafka server side to > avoid this. -- This message is automatically generated by JIRA.
