Buğra Gedik updated KAFKA-2392:
-------------------------------
Description:
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.
