There could be a problem with the certificate itself. I recommend regenerating it and trying again. You can follow instructions in the Apache Knox Users Guide to generate a self-signed certificate: http://knox.apache.org/books/knox-0-6-0/user-guide.html#Generating+a+self-signed+cert+for+use+in+testing+or+development+environments If you want to use a more legitimate certificate you can generate and sign it yourself with OpenSSL or from a CA, and follow the steps in the next section of the guide, Using a CA Signed Key Pair. ...

The only way to reliably accomplish this is to prevent users from logging into cluster nodes at all, and force them to use beeline to access HS2 in HTTP mode through Knox. Every solution recommending changes to hive-env.sh or hive.distro can be overridden by using a modified copy of those files. Those files could even be copied from elsewhere, because this is all open source. ... View more

Re: Multiple Knox gateways?

Running each topology on its own Gateway instance is fine, but it's not necessary. You can use a single Knox Gateway instance and simply create a separate topology per-AD. Say you have 2 topologies, ad1 and ad2, then you can connect using: https://knox-host:8443/gateway/ad1/<service>/. https://knox-host:8443/gateway/ad2/<service>/. ... View more

This feature is tracked in YARN-2477 (DockerContainerExecutor must support secure mode). There is currently no fix version specified. Docker container support on YARN is still very new, so you might want to follow the umbrella JIRA, (YARN-2466) to gain an idea of when additional features might become available. ... View more

Sagar's answer is the best solution if both clusters will use the same AD. If each cluster has its own AD with unique users and groups, then you should clarify what you are hoping to gain by duplicating the policies. Keeping in mind that you'll need to sync them on an ongoing basis, it seems like "updating" every policy for a new set of users/groups would be more work than manually adding the policies on each cluster. ...

It sounds like there are two conflicting goals you might want to achieve. Is the intention to migrate cluster-B/2 to use the same AD as cluster-A/1? Or do all users have accounts in both ADs, and you want to translate the policies from A to B but keep them on different ADs? ... View more
