Hi Vignesh I am not sure what you mean by UNIX IDs is. Do you mean User ID (UID) which is the ID (number) of a given user? If so, there is no real requirement. You can run as root, or you can run as a user you create, provided that it has read and write access to a set of directories (data, logs etc...). Best security practice would say that you shouldn't run as root. Depending on how you installed Kafka and Zookeeper, it could be that the install packager already created a corresponding user (kafka, zookeeper) and already set the appropriate permissions to the directory it should write to. If you just untarred a binary archive, then it will be up to you to set the permissions.
Hope it helps! Cheers, Christophe On 27 March 2018 at 08:55, Vignesh <davidviki...@gmail.com> wrote: > Hi Christophe, > > No, not the PIDs...
