Manikumar resolved KAFKA-2392. ------------------------------ Resolution: Fixed Kafka supports port 0 for unit tests. As mentioned in the previous comment, Curator's TestingServer to run an in-memory Zookeeper, > Kafka Server does not accept 0 as a port > ---------------------------------------- > > Key: KAFKA-2392 > URL: https://issues.apache.org/jira/browse/KAFKA-2392 > Project: Kafka > Issue Type: Bug > Components: config > Affects Versions: 0.8.2.1 > Reporter: Buğra Gedik > Priority: Minor > > I want to specify 0 as a port number for Zookeeper as well as Kafka Server. > For instance server.properties configuration file has a 'port' property, but > does not accept 0 as a value. Similarly, zookeeper.properties has a > 'clientPort' property, but does not accept 0 as a value. > I want 0 to specify that the port will be selected automatically (OS > assigned). In my use case, I want to run Zookeeper with an automatically > picked port, and use that port to create a Kafka Server configuration file, > that specifies the Kafka Server port as 0 as well. I parse the output from > the servers to figure out the actual ports used. All this is needed for a > testing environment. > Not supporting automatically selected ports makes it difficult to run Kafka > server as part of our tests. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
