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) Internal error processing describe_ring java.lang.NullPointerException at org.apache.cassandra.service.StorageService.getRangeToRpcaddressMap(StorageService.java:623) at org.apache.cassandra.thrift.CassandraServer.describe_ring(CassandraServer.java:731) at org.apache.cassandra.thrift.Cassandra$Processor$describe_ring.process(Cassandra.java:3664) at org.apache.cassandra.thrift.Brisk$Processor.process(Brisk.java:464) at org.apache.cassandra.thrift.CustomTThreadPoolServer$WorkerProcess.run(CustomTThreadPoolServer.java:187) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) -- This message is automatically generated by JIRA.
