>          Issue Type: Bug
>          Components: connectors
>    Affects Versions: 1.4.5
>         Environment: cdh5.3.2
>            Reporter: Suresh
>              Labels: AVRO, SQOOP
>             Fix For: 1.4.5

> When a Special character like '$' or  '#' are present in column name, sqoop/avro removes those special character. In some cases it leads to duplicate column.
> e.g. If we have COL$1 and COL1$ in the schema, it removes both of them and creates the duplicate column as COL1 and it results in failure of the SQOOP import job as a avro data. The same table can be loaded without --as-avarodata flag.
> The similar issue is raised in, https://issues.apache.org/jira/browse/SQOOP-1361 - which i suppose is fixed and the fix is creating this new issue.
