Reynold Xin commented on SPARK-6229:
------------------------------------
I haven't read through the various discussions here since they are long, but I
just want to point out that it would be great to build it in a way that we can
swap out encryption handlers, e.g. maybe just take an extra Netty handler for
encryption, or expose the pipeline for users to manipulate. The use case would
be to make this pluggable so we can support SSL in addition to SASL.
> Support encryption in network/common module

> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Reporter: Marcelo Vanzin
>
> After SASL support has been added to network/common, supporting encryption
> should be rather simple. Encryption is supported for DIGEST-MD5 and GSSAPI.
> Since the latter requires a valid kerberos login to work (and so doesn't
> really work with executors), encryption would require the use of DIGEST-MD5.
