VISHNU S NAIR updated SQOOP-2561:
---------------------------------
Comment: was deleted
(was: Hi [~jarcec],
SQOOP-2839 : I think there won't be a problem in case of tables with columns
PROTOCOL_VERSION and _PROTOCOL_VERSION. Because we are adding an extra under
score in case of columns start with "_". So the columns in the class will be in
"_PROTOCOl_VERSION" and "__PROTOCOL_VERSION.".
Could please go through "toJavaIdentifier()" method in ClassWriter
)

> Project: Sqoop
> Issue Type: Bug

> Environment: cdh5.3.2

>
> 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.
