Subject [jira] [Commented] (SPARK-6229) Support encryption in network/common module
Date Tue, 17 Mar 2015 04:44:38 GMT

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.

> 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.
