AssertionError when adding a node and doing repair, repair hangs
----------------------------------------------------------------

                 Key: CASSANDRA-3369
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3369
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.0.0
         Environment: Ubuntu Linux amd64, 1.0.0-rc2
            Reporter: Christian Spriegel


Hi again,

I was playing aroung with Cassandra 1.0.0-rc2 and got an AssertionError. The cluster I set
up was two cassandra nodes on one laptop using different 127.0.0.* loopback devices. Both
nodes have separate folders on the harddisk.


Here is what I did:


1. Started node1 and inserted some data into it using a simple singlethreaded testprogram
(uses hector 0.8.0-2):
127.0.0.1       datacenter1 rack1       Up     Normal  583.55 MB       100.00% Token(bytes[63e5b6995466cd3221cba16646ae19ed])

2. I started another node, node 2 = 127.0.0.2:
127.0.0.2       datacenter1 rack1       Up     Normal  147.57 KB       50.00%  Token(bytes[4d6ccfeaa8bb59551751a2816fde9343])
127.0.0.1       datacenter1 rack1       Up     Normal  583.55 MB       50.00%  Token(bytes[63e5b6995466cd3221cba16646ae19ed])

3. I triggered a "nodetool -h 127.0.0.1  repair" on the first node that had the data from
my test.


This repair does not seem to ever end. The nodetool is hanging now but my computer is idle.
I get an AssertionError on the first node:
java.lang.AssertionError
