> Key: KAFKA-7037
> URL: https://issues.apache.org/jira/browse/KAFKA-7037
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.10.1.0, 1.0.0
> Reporter: Sandeep Nemuri
> Priority: Major
>
>
> {code:java}
> [kafka@localhost ~]$ /usr/hdp/current/kafka-broker/bin/kafka-topics.sh
> --create --zookeeper `hostname`:2181 --replication-factor 1 --partitions 1
> --topic test+topic
> Created topic "test+topic".
> [kafka@localhost ~]$ /usr/hdp/current/kafka-broker/bin/kafka-topics.sh
> --zookeeper `hostname`:2181 --list
> __consumer_offsets
> test+topic
> [kafka@localhost~]$ /usr/hdp/current/kafka-broker/bin/kafka-topics.sh
> --zookeeper `hostname`:2181 --delete --topic test+topic
> Error while executing topic command : Topic test+topic does not exist on ZK
> path ssltester-3.openstacklocal:2181
> [2018-06-11 09:36:32,989] ERROR java.lang.IllegalArgumentException: Topic
> test+topic does not exist on ZK path ssltester-3.openstacklocal:2181
> at kafka.admin.TopicCommand$.deleteTopic(TopicCommand.scala:166)
> at kafka.admin.TopicCommand$.main(TopicCommand.scala:68)
> at kafka.admin.TopicCommand.main(TopicCommand.scala)
> (kafka.admin.TopicCommand$)
> {code}
> The major issue is that while executing a delete command kafka cli tool is
> removing the "+" symbol and deleting the incorrect topic. In below case if
> _"*test+topic"*_ is deleted kafka deletes _*testtopic.*_
> {code:java}
> [kafka@localhost~]$ /usr/hdp/current/kafka-broker/bin/kafka-topics.sh

> Created topic "testtopic".
> [kafka@localhost~]$ /usr/hdp/current/kafka-broker/bin/kafka-topics.sh
> --zookeeper `hostname`:2181 --topic test+topic --delete
> Topic testtopic is marked for deletion.{code}

> It seems create topic doesn't check for '+' and delete topic replaces '+'
> from the topic name.
