Subject [jira] [Commented] (ACCUMULO-1009) Support encryption over the wire
Date Thu, 19 Sep 2013 15:58:51 GMT


Keith Turner commented on ACCUMULO-1009:

I just spent a bit looking at a patch.  And I see a new one was posted recently, these may
be against the older one.  It would be nice to post multiple version of the patch and then
I could state that my comments are against version 002 of the patch.

 * what does certutils do that keytool does not? or does it just make things easier?  How
do you expect the user to run this?  "accumulo"
?   If this is the case, then this utility is not front and center and the user would really
have to look for it.
 * should generate all print a disclaimer clearly stating any potential pitfalls/risk the
user should be aware of?  [~ctubbsii] would this address your concern?
 * Adding ssl options to MAC is done to test Accumulo itself.  However this will also be available
to Accumulo users using MAC.  Is this an API you feel comfortable supporting for a few years?
 * I am not in favor of adding "public ZooKeeperInstance(String instanceName, String zooKeepers,
boolean sslEnabled)".  This is not a scalable approach for configuring Accumulo.  For example
when ACCUMULO-1268 is implemented we would not want constructors for : (..., sslEnabled),
(...,sslEnabled,timeout), (...,timeout) .  I think the constructors that take ClientConfiguration
are sufficient and ClientConfiguration looks nice, like it.  I am kinda torn about making
client and sever config follow differnt models, but the new client config seems better.  I
still need to look at it in more detail.
 * what needs to be done for the proxy w.r.t to ssl?  should ClientConfiguration be exposed
to proxy api?  should proxy server support ssl? maybe we should create sub-tickets
Seems like we need test for the following scenarios :

 * Server requires clients have cert signed by trusted CA (test client w/ valid cert, w/o
cert, w/ invalid cert)
 * Server requires SSL, client tries connecting w/o SSL
 * Server does not have a cert that client trust
 * Multiple ZooKeeperInstances in the same java process with different SSL config (is this
possible? It looks like you included ssl options in the Key in ThriftTransportPool?)  This
could happen if a single process connected to multiple Accumulo instances
