----------------------------------
Summary: 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 acce[t 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 a 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.
