Delete clustering information that references zookeeper and helix

[FireBurn]

It is totally inaccurate now, zookeeper and helix support was removed from Appformer 3 years ago

It should probably be replaced with something regarding NFS but I'm still figuring that out

Thanks for this @FireBurn ! If you're proposing to remove that section, then a few additional things are required:

• Search the project for any references to the anchor ID or file name for that section file and the corresponding chap file to ensure any cross-references are updated or removed.
• Address or remove the corresponding chapter that includes that section file, here https://github.com/FireBurn/kie-docs/blob/patch-2/doc-content/shared-kie-docs/src/main/asciidoc/Workbench/WorkbenchHighAvailability-chapter.adoc
• Remove the include to that chap file if that is also removed

But, relevant replacement content would be optimal anyway.

@csherrar @kaldesai Which one of you would this apply to? Can you add the relevant SME(s) to verify as well? See also #2805

Thanks guys.

I wasted quite a lot of time figuring out zookeeper and helix and and even longer time trying to figure out why clustering wasn't working with it, I'll hopefully have clustering figured out in the next week or so, and will try and write something up

Is someone already working on this? It seems like quite a big bit of functionality to be wrong for so long

@FireBurn Right, understood. I've pinged the relevant writers to see if they have any info on this or if they know who the relevant devs would be to ping here from community. Thanks.

@vidya-iyengar @heathjoy FYI as well.

[csherrar]

@sterobin Ack, pinging SMEs.

@sutaakar @domhanak @dgutierr Do you know who the relevant devs would be to ping here from community?

Example doc link

[sutaakar]

I have no idea

[domhanak]

Imho this can go away, zookeeper was used with older versions, in current time it is obsolete.
However, a doc that says how to do it now, should be reinstated in its place.

[csherrar]

@domhanak Can you look over the Clustering Doc please and let me know if there is anything that aligns with this section's purpose? @FireBurn mentioned NFS.

Installing and configuring RHPAM/RHDM in a EAP clustered environment - Configuring an NFS server

[domhanak]

@tomasdavidorg could you please look at above comments? Is there a possibility to have community doc for this?

[tomasdavidorg]

Running RHPAM on clustered environment (NFS file system) is tech preview right now. I think this can be replacement for zookeeper/Helix in community.

[sterobin]

@FireBurn See above comments.

[sterobin]

@csherrar or @kaldesai , can you coordinate with @FireBurn and the relevant SMEs to see what needs to happen here and by whom? Same with #2805 . Both PRs seem to be at a standstill.

@vidya-iyengar @heathjoy FYI as well.

[domhanak]

The docs still reference zookeeper and helix in 7.56.0 (and no doubt 7.57.0 when it's tagged) when support was removed back in 7.5.0 (kiegroup/appformer@f8e4602) back in 2017 via https://issues.redhat.com/browse/AF-894
