> the error happens in

> generateCreateTableStatement,where the second parameter storageDfsDir defined
> in getMetadataUrlPrefix from
> ./common/src/main/java/org/apache/kylin/common/KylinConfig.java
> hdfs don't allow special colon in hdfs url path,so hive related create table
> ddl with location can't be executed
