Subject Re: kylin2.6.4流式构建不能与hdp3.1.4.0使用(issue3970)
Date Thu, 24 Oct 2019 16:12:40 GMT
I remanufactured a small amount of data, tested and modified the MapReduce configuration, but
the same error still occurred。
    Fortunately, I found some additional error logs on the yarn cluster. This error log is
the same as that mentioned in issue 3970. After modifying mapreduce.tar.gz to delete kafka-clients-0.8.2.1.jar,
more conflicts will occur. The error logs are as follows

     This issue 3970 doesn't mention how to solve the new conflicts brought by it. Can you
tell me how to solve the bug brought by guava?
