> Key: KYLIN-4856
> URL: https://issues.apache.org/jira/browse/KYLIN-4856

> Issue Type: Bug
> Components: Website
> Affects Versions: v3.1.1
> Reporter: yoonsung.lee
> Assignee: Yaqian Zhang
> Priority: Major
>
> Hi. I'm yoonsung.lee
> I'm trying to apply distributed multiple job schedulers to my cluster.
> But the explanations of distributed multiple job schedulers are different between the website and cwiki.
> h3. Website
> The website ({color:red}Enable multiple job engines (HA){color} section in {color:#0747A6}http://kylin.apache.org/docs/install/advance_settings.html{color}) guide to configure
> {code}
> kylin.job.scheduler.default=2
> kylin.job.lock=org.apache.kylin.storage.hbase.util.ZookeeperJobLock
> {code}
> for multiple job engines.
> h3. Cwiki
> The cwiki ({color:#0747A6}https://cwiki.apache.org/confluence/display/KYLIN/Comparison+of+Kylin+Job+scheduler{color}) says the *DistributedScheduler* (which is set as *kylin.job.scheduler.default=2*) uses ZookeeperDistributedLock as implementation class.
> But the website guides to set *kylin.job.lock=org.apache.kylin.storage.hbase.util.ZookeeperJobLock* which is described as DefaultScheduler in cwiki.
> h1. Solution
> If the cwiki is right, the description on the website should be changed.
> If the website is right, the description on the cwiki should be changed.
> Please let me know if I misunderstand for setting distributed multiple job schedulers.
