Hi Kylin developer, my hadoop environment : HDP 2.6 Kylin2.0
When I try to add datasource, Kylin sync hive table is okey. But, when I try to build the cube, I got error at setp 3 as follow: *Caused by: org.datanucleus.exceptions.NucleusException: Attempt to invoke the "BONECP" plugin to create a ConnectionPool gave an error : The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the CLASSPATH.
