Re: Testing 4.0 upgrading


Hi Tommy,

Thank you for taking the time to start kicking the tires on the upgrade to
4.0. It looks like you've found two bugs:

1) "Unknown column coordinator_port during deserialization" (reported on
3.x nodes)

- looks like the 4.0 node isn't filtering out a column from a system table
that 3.0 doesn't know about. Most likely due to CASSANDRA-7544. Can you
open a JIRA for this, and tag @aweisberg?

2) SSL connection problems

I unserstand the 4.0 -> 3.X connection problem, and documented it at [1] in
MessagingService. TL;DR we don't know the version of a peer when restarting
and need to wait for that peer to connect to the local node and pass it's
correct messaging version (if the local node cannot interpret the handhsake
from the peer). However, why for the inbound connection to the 4.0 node it
is seeing SSLv2 is unclear. Can you open a separate JIRA, and we'll go from
there? In the meantime, maybe enable the JDK's SSL debugging [2] on the 3.x
node to see exactly what it is trying to do? Also, you can enable wire
tracing on the 4.0 node by setting this value to true [3] and recompiling.
We can followup further in the jira.

Thanks!

-Jason
