Hi: The problem of error reporting looks like jar package conflict, It may be due to the inconsistency between the versions of the classes in MRS3.0.5 environment and the classes to be loaded by kylin. And we have not adapted to the cloud environment in China, class conflict should be a common phenomenon. You can add `-verbose:class` at $KYLIN_HOME/conf/setenv.sh to print the progress of load class.
