    Hi @gireeshp ,
    Sqoop project currently does not accept pull requests. To contribute, you will need to generate patch and upload it to the JIRA.
    See the instructions here: [https://cwiki.apache.org/confluence/display/SQOOP/How+to+Contribute](https://cwiki.apache.org/confluence/display/SQOOP/How+to+Contribute)
    If you need more directions, I'd be happy to help!

> Did a sqoop import from mysql table "emp", with split-by column "ename", which is a varchar(100) type.
> +Used below command:+
> sqoop import --connect jdbc:mysql://localhost/testdb --username root --password ***** --table emp --m 2 --target-dir /sqoopTest/5 --split-by ename;
> +Ename has following records:+
> | ename   |
> | gireesh |
> | aavesh  |
> | shiva'  |
> | jamir   |
> | balu    |
> | santosh |
> | sameer  |
> Min value is "aavesh" and max value is "shiva'" (please note the single quote inside max value).
> When run, it tried to execute below query in mapper 2 and failed:
> SELECT `ename`, `eid`, `deptid` FROM `emp` AS `emp` WHERE ( `ename` >= 'jd聯聭聪G耀' ) AND ( `ename` <= 'shiva'' )
