Subject [jira] [Created] (CASSANDRA-5270) IllegalArgumentException during loading system schema
Date Tue, 19 Feb 2013 15:03:14 GMT
Aleksander Stasiak created CASSANDRA-5270:

             Summary: IllegalArgumentException during loading system schema
                 Key: CASSANDRA-5270
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.7
         Environment: Linux 3.6.9-2.fc17.x86_64 #1 SMP Tue Dec 4 13:26:04 UTC 2012 x86_64
x86_64 x86_64 GNU/Linux

            Reporter: Aleksander Stasiak

The scenario was as follows: 
I tried to to create test keyspace with the copy of production data (production data had simple
topology with RF:2). Both should be stored in the same cluster. I dropped old test keyspace
with command: drop keyspace production; result - positive, so I removed test folder from data.
Then I executed flush on all servers and copied production folder from data into the test
and renamed all files with prefix production to test.
After it I created test storage with RF:1 (topology: simple). Then I started to verify consistency
with scripts, but on one of the servers log message appeared:
AssertionError: DecoratedKey(long list of keys) != DecoratedKey(104348225353174882702076782103426695837,
6e6e636c5776665f6f61695f6574646d73) on one of test files
so I decided to restart, But node declined to start with error message:
