Subject [jira] [Commented] (CASSANDRA-11991) On clock skew, paxos may "corrupt" the node clock
Date Tue, 21 Jun 2016 22:53:57 GMT


Jason Brown commented on CASSANDRA-11991:

lgtm. The only minor nit I have is CASSANDRA-9649 made {{ClientState#lastTimestampMicros}}
a static field. I believe this change helped accelerate the cluster get into a bad state wrt
the propagation of bad timestamps. wdyt about switching it back to being an instance field
(not static)?

> W made a mistake in CASSANDRA-9649 so that a temporal clock skew on one node can "corrupt"
other node clocks through Paxos. That wasn't intended and we should fix that. I'll attach
a patch later.
