> I've set up  Kylin to access a SQL server using JDBC and do the ETL step as described in
> [http://kylin.apache.org/docs/tutorial/setup_jdbc_datasource.html]
> but when the "Sqoop To Flat Hive Table" runs it terminates with an error shown in the attached log.
> It seems that the root cause is the presence of the '`' character in the query, which has no meaning for sql server.
>  
> My problem seems to related to this piece of code
>  
> public class FlatTableSqlQuoteUtils {
> public static final String QUOTE = "`";
> /**
>  * Quote identifier by default quote `
>  * @param identifier
>  * @return
>  */
>  public static String quoteIdentifier(String identifier){
>  return QUOTE + identifier + QUOTE;
>  }
>  
> The solution may be to add a parameter to change this character used for quoting.
>  
> Just to be sure I made a copy of the original "sqoop" command to "sqoop.orig" and replaced the original with a little script of mine (attached).
> This little script removes the "`" character from the original command and the call "sqoop.orig" with the cleaned arguments.
> It works, but it is still an ugly workaround.
