> Container link broken on Spark UI Executors page when YARN is set to
> HTTPS_ONLY
> -------------------------------------------------------------------------------

> Key: SPARK-6868
> URL: https://issues.apache.org/jira/browse/SPARK-6868

> The stdout and stderr log links on the executor page will use the http://
> prefix even if the node manager does not support http and only https via
> setting yarn.http.policy=HTTPS_ONLY.
> Unfortunately the unencrypted http link in that case does not return a 404
> but a binary file containing random binary chars. This causes a lot of
> confusion for the end user since it seems like the log file exists and is
> just filled with garbage. (see attached screenshot)
> The fix is to prefix container log links with https:// instead of http:// if
> yarn.http.policy=HTTPS_ONLY. YARN's job page has this exact logic as seen
> here:
