Re: Kylin 2.6.4 error when building cubes with hadoop 3.1.3
Hi, Do you use Kylin in CDH 6.3? I have heard one user deploy Kylin on CDH 6.3 and met the same problem?

I’m facing following errors at the third step when building a cube (Kylin_Fact_Distinct_Columns): [cid:image001.png@01D59BCF.A2D5BDF0] The versions of my environment is as follows: [cid:image002.png@01D59BCF.A2D5BDF0] I think it’s maybe a problem caused by guava versions. Hadoop 3.1.3 used guava-27.0，but kylin call function from guava versions less than guava-16. So, how can I fixed this problem. Thank you! Best Begards, Sunshine
