> 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: https://github.com/apache/hadoop/blob/e1109fb65608a668cd53dc324dadc6f63a74eeb9/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app/src/main/java/org/apache/hadoop/mapreduce/v2/app/webapp/JobBlock.java#L108
