>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: operators
>    Affects Versions: 1.10.2
>            Reporter: Francesco Macagno
>            Assignee: Galak
>            Priority: Minor
>             Fix For: 1.10.6

>
> When using an operator that has Jinja templating enabled for a field, if the field value ends with a newline then the newline is removed, regardless of whether there was a template in the string.
>  
> This came up when attempting to send data to Prometheus pushgateway using the SimpleHttpOperator. Pushgateway requires a newline at the end of every entry, so the removal of the newline at the end of the data parameter causes the request to fail in a way that is difficult to debug.
>  
> This can be gotten around by including a space after the newline character, though this is not a great solution. The space is ignored by pushgateway.
