    fix the import database_name.table_name from path

    detail :
    use test;
    create table a(id int,name string);
    export table a to '/tmp/a';
    drop table a;
    import table test.a from '/tmp/a';
    hive> import table test.a from '/tmp/a';
    Failed with exception Invalid table name test.test.a
    FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MoveTask
    
    when use import database_name.table_name from ,
    the tblDesc.getTableName() return database_name.table_name ,not table_name
    Table table = new Table(dbname,database_name.table_name) will return the table's name is dbname.database_name.table_name
    correct table name should be test.a,not   test.test.a
    
    we can fix this:
      String[] dbTableName =Utilities.getDbTableName(dbname,tblDesc.getTableName());
       Table table = new Table(dbTableName[0], dbTableName[1]);
