Can I run "refresh <table>" through JDBC driver?

I tried and it didn't work. Is there a way to send refresh through JDBC
driver?

   val impalaUrl = "jdbc:hive2://impala:21050/default1;auth=noSasl"

   val driverClass = Class.forName("org.apache.hive.jdbc.HiveDriver")

   val conn = DriverManager.getConnection(impalaUrl)

   val st = conn.createStatement()
   st.execute("refresh my_table")

   conn.close

Exception in thread "main" java.sql.SQLException: AnalysisException: Syntax
error at:

^
