Re: cube can't building in flink 1.11.3 / 1.10.0

[Yaqian Zhang]

Hi:

Kylin version 3.1.1 supports Flink 1.9.x.

If you want to use Flink 1.10.0 or 1.11, someone in the Kylin community 
recently proposed the PR  https://github.com/apache/kylin/pull/1462 to upgrade 
Flink.

You can type this patch and try again.
