> Improve error message generated in DataDrivenDBInputFormat when no splitter
> is available
> -----------------------------------------------------------------------------------------
>
> Key: SQOOP-652
> URL: https://issues.apache.org/jira/browse/SQOOP-652
> Project: Sqoop
> Issue Type: Bug
> Affects Versions: 1.4.2
> Reporter: Jarek Jarcec Cecho
> Assignee: Linden Hillenbrand
> Priority: Trivial
> Labels: newbie
> Fix For: 1.4.3
>
>
> Currently DataDrivenDBInputFormat will throw following exception in case that
> there is no available Splitter:
> {code}
> DBSplitter splitter = getSplitter(sqlDataType);
> if (null == splitter) {
> throw new IOException("Unknown SQL data type: " + sqlDataType);
> }
> {code}
> Text of the exception is very confusing as it's not describing what has
> actually happened. Would be great if this message would be improved by saying
> that Sqoop do not have splitter for given sql type and therefore user should
> either use different split column (argument --split-by) or lower number of
> mappers to 1 (splitters are not used in such case).
