It is extremely rare that configuration files under /usr need to be edited. Page 152 (http://docs.redhat.com/docs/en-US/Red_Hat_Storage/2.0/html-single/Administration_Guide/index.html#id3047004) tells to make changes in /usr/share/java/conf/core-site.xml. I am wondering if there is not a better suitable file under /etc that can be used to overload the configuration. (Ah, page 153 tells to create a sym-link to the configuration directory. Maybe it's better practise to not link, but copy the configuration?)
AJ mentioned that /usr/share/java is where jars get installed. You're right, that need not be the path for the configuration file. If /etc makes more sense for configuration files, I'm okay in moving core-site.xml somewhere there. Regarding the sym-link thing, that's how we wanted it with upstream GlusterFS. If it's a good practice (RHS?) in copying the file over, then docs need to be updated.
Niels, Based on my discussion with VS and Venky, it was decided to move core-site.xml file to /var/lib/glusterd/. We will request AJ to move it and then update the doc. Kindly confirm if copying the configuration file is the best practice instead of linking. Based on your confirmation, I will update the doc. Regards, Divya
Hi Divya, yes, copying a file from /usr/... to /var/lib/.. is fine. Contents under /usr should not be edited by administrators, /var/lib is definitely a better place for that. It is possible that the original file under /usr/... is kept, and the administrator manually copies the file to /var/lib/... Automatically would be good too, but I don't know how practical that is. Thanks, Niels
lets keep it in /var/lib/glusterd/glusterfs-hadoop/ administrator can manually copy the conf from this directory to whatever his $HADOOP_HOME is. AJ, the spec file would need to change to drop the conf in the above mentioned directory.
As suggested, I have changed instructions to copy files to respective location instead of creating symbolic links. The updated documentation is available at: http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_Storage/2.0/html/Administration_Guide/sect-Administration_Guide-GlusterFS_Client-CIFS.html#id1257909 Cloning this bug for Release Engineering to move the file to /var/lib/glusterd/glusterfs-hadoop/.
Moving this bug to VERIFIED state
Since this bug is blocked by 854541 - again moving this bug to ON_QA state
First part of this bug is fixed - [ Copying instead of creating symbolic link] - is verified, but the latter part of moving the file /usr/share/java/conf/core-site.xml to /var/lib/glusterd/glusterfs-hadoop/core-site.xml will tracked seperately, as it is not yet implemented, in a new bug as discussed with Divya. So moving this bug to VERIFIED state
