NPE in describe_ring
--------------------
Key: CASSANDRA-3023
URL: https://issues.apache.org/jira/browse/CASSANDRA-3023
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.8.4
Reporter: Eric Falcao
Not sure how much of the following is relevant besides the stack trace, but
here I go:
I have a 2 DC, 2 node per DC cluster. DC1 had it's seed replaced but I hadn't
restarted. I upgraded to 0.8.4 in the following fashion:
-edited seeds
-stopped both DC1 nodes
-upgraded jars
-started both nodes at the same time
The non-seed node came up first and showed the following error. Then when the
seed node came up, the error went away on the non-seed node but started
occurring on the seed node:
ERROR [pool-2-thread-15] 2011-08-12 22:32:27,438 Cassandra.java (line 3668)
