> The code piece which causes the issue is in [*{{SqoopActionExecutor.java}}*|https://github.com/apache/oozie/blob/master/core/src/main/java/org/apache/oozie/action/hadoop/SqoopActionExecutor.java#L89-L117]:

>         // However, we do not do this if the command looks like

> {code}
> Since the delimiter is a space, the code splits the {{select * from table into select, *, from, table as nextToken}} and adds them separately into the array causing the issue.
>  
> I have made a code change locally to address this issue and did some testing around this and it seem to work fine, hence submitting the code change for this.
