Review request for kylin, Dayue Gao, hongbin ma, and Wang Xiaoyu.
Bugs: KYLIN-2557
https://issues.apache.org/jira/browse/KYLIN-2557
Repository: kylin
Description
-------
Muliple instances were started at the same time after we installed the kylin. A
conflict will occurs because these instances cteate kylin_metadata_acl table at
the same time. The result is that the kylin start failed. The error log is as
following:
