You're just showing us an error... What are you trying to do, what do you want to achieve? - Ray
I use url jdbc:kylin://.../mydb to access remote db. - tommy
this.kylinJdbcTemplate.queryForList("select * from table limit 1"); this is the sql statement for the query. - tommy
Then I run the example from kylin website, also has the same error above. - tommy

this error is only at kylin-jdbc-1.5.2.jar. When I use kylin-jdbc-2.1.0.jar, the above issue was settled.
