Subject [jira] [Created] (KYLIN-4290) Add file lock to kylin startup script to avoid starting multiple instances on one node
Date Tue, 10 Dec 2019 11:59:00 GMT
Zheng Yang created KYLIN-4290:
---------------------------------

             Summary: Add file lock to kylin startup script to avoid starting multiple instances
on one node
                 Key: KYLIN-4290
                 URL: https://issues.apache.org/jira/browse/KYLIN-4290
             Project: Kylin
          Issue Type: Improvement
          Components: Tools, Build and Test
    Affects Versions: v3.0.0, v2.6.5
            Reporter: Zheng Yang
             Fix For: v2.6.0


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.
