-------------------------------------

             Summary: Kafka doesn't allow to delete topic with '+' in the name
                 Key: KAFKA-7037
                 URL: https://issues.apache.org/jira/browse/KAFKA-7037
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.10.1.0
            Reporter: Sandeep Nemuri


 
{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

{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 --create 
--zookeeper `hostname`:2181 --replication-factor 1 --partitions 1 --topic 
testtopic
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.

Create Topic: 
[https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/internals/Topic.java#L77-L85]
 

Delete Topic : 
[https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/consumer/TopicFilter.scala#L28-L33]
