Subject [jira] [Commented] (AIRFLOW-161) Redirection to external url
Date Mon, 23 May 2016 19:38:12 GMT

    [ https://issues.apache.org/jira/browse/AIRFLOW-161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15296944#comment-15296944

Chris Riccomini commented on AIRFLOW-161:
-----------------------------------------

What context is this under? You mean like you want to use the EmailOperator or SlackOperator
to notify people to download a file that's been created as part of the DAG?

We do this using XCom+EmailOperator. XCom variables can be accessed via templates. We store
the file in a blob store (like S3). The file location is stored in XCom, which the EmailOperator
references when it sends the email.

> Hi,
> I am not able to find a good way (apart from loading everything upfront), where I can
redirect someone to a external service url, using the information stored in airflow. There
could be many use cases like downloading a signed file from s3, redirecting to hadoop job
tracker, or a direct case on which I am working which is linking airflow tasks to qubole commands.

> I already have a working model and will open a PR soon. Please let me know if there existing
ways already.
> Thanks,
> Sumit
