network/shuffle/src/main/java/org/apache/spark/network/sasl/SparkSaslServer.java

This is a change from the prior version -- before, only the client did this transformation, now both the server and client do.

I don't follow your comment? It used to encode it for both client and server before as well.

It seems bad if you are trying to do a sasl negotiation with a null password.

I'm referring to this: https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkSaslClient.scala#L118

I'm not sure what should be done about the case where both sides have a null password. Could throw exceptions on both sides.

This looks good pretty to me. @tgravescs it would be great if you can take a look since you wrote the original sasl code. Thanks.

network/shuffle/src/main/java/org/apache/spark/network/sasl/SparkSaslClient.java

Why was this (and other classes) changed to java?

For inclusion in the YARN node manager with minimal dependencies (no dependencies on Spark or Scala).

tgravescs · 2014-11-04T15:52:04Z

Nothing major was jumping out at me. I haven't had time to look at the netty implementation in detail though either.

Did you do any manual testing? I would suggest creating some external process and just trying to hack the connection (pass bad password, auth off, etc) just as a full integration test.

tgravescs · 2014-11-04T16:14:50Z

network/common/src/main/java/org/apache/spark/network/util/TransportConf.java

we should document this config

Documentation for all network-related things is forthcoming soon, we don't have a place for it within this patch.

aarondav · 2014-11-04T17:06:48Z

Addressed all non-documentation and testing related comments, I will work on those soon. For testing, I just need to add a NettyBlockTransfer-level integration test which matches the ConnectionManager's equivalent one.

@tgravescs @rxin Thanks for the review, I believe I've addressed all comments and I've added a full end-to-end test at the NettyBlockTransfer level.

Merging this in master.

@tgravescs would be great if you continue looking at the new code. If you find new problems or have suggestions on better implementation/design, we will create new PRs to address them.

rxin · 2014-11-04T19:03:56Z

ASF git is down at the moment. Will merge when it comes back up.

network/shuffle/src/main/java/org/apache/spark/network/sasl/SaslMessage.java

Hey question, should this be fully public? Is it because there's no private[spark] equivalent in Java and we need to access it outside of its package?

I wonder if we should mark this @DeveloperAPI or something to prevent people from using it themselves.

This is actually package-private and is not accessible outside the package. In general, your point still stands, though, and there are other places where we are public because it must be accessed from a diff. package. We should have such an annotation.

Oh yeah, sorry, this is package-private. I'm referring to SparkSaslServer and SparkSaslClient

Gotcha, yeah, we need to figure out a scheme for @DeveloperAPI in this module....

andrewor14 · 2014-11-04T19:46:55Z

LGTM. If there are any outstanding issues we can fix them in subsequent patches.

We shouldn't add developer api tag because this whole package should be private and not exposed to users. We should exclude this from all public docs.

Also lays the groundwork for supporting it inside the external shuffle service.
