Summary: add parameter to change sql quoting character for sqoop
Key: KYLIN-3857
URL: https://issues.apache.org/jira/browse/KYLIN-3857
Project: Kylin
Issue Type: Bug
Reporter: Davide Malagoli
Attachments: sqoop-error.log, sqoop-script.sh
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.
