> Key: KYLIN-4290
> URL: https://issues.apache.org/jira/browse/KYLIN-4290
> Project: Kylin
> Issue Type: Improvement
> Components: Tools, Build and Test
> Affects Versions: v2.6.0
> Reporter: Zheng Yang
> Assignee: Zheng Yang
> Priority: Minor
> Fix For: v2.6.5, v3.1.0
>
>
> When we restart the Kylin instance, due to the slow start of kylin, some
> monitoring scripts fail to detect the surviving kylin, and will also start
> the kylin instance. As a result, there are multiple kylin instances on a node.
> By adding a file lock to the startup script (kylin.sh), it is guaranteed that
> only one kylin instance will be started when concurrent startup on a node.
