-----------------------------------------
Summary: timout excpetion in client side and AssertionError in
cassandra log
Key: CASSANDRA-4407
URL: https://issues.apache.org/jira/browse/CASSANDRA-4407
Project: Cassandra
Issue Type: Bug
Components: API, Core
Affects Versions: 1.0.10, 1.0.8
Environment: Debian linux
Reporter: Nare Gasparyan
Priority: Critical
Hello.
I moved my cassandra from one sever to another. Cassandra's version on the
first server was 1.0.8 on the new one it is 1.0.10. I moved also data by
copying all files under /var/lib/cassandra/data/mykeyspace.
and now it seems to me that some data has been corrupted during migration as I
get the following exceptions when getting data for some keys.
In cassandra client I get
me.prettyprint.hector.api.exceptions.HTimedOutException: TimedOutException()
at
me.prettyprint.cassandra.service.ExceptionsTranslatorImpl.translate(ExceptionsTranslatorImpl.java:42)

at
me.prettyprint.cassandra.service.Operation.executeAndSetResult(Operation.java:103)
In cassandra system.log I get
ERROR [ReadStage:492] 2012-07-02 21:50:50,280 AbstractCassandraDaemon.java
(line 139) Fatal exception in thread Thread[ReadStage:492,5,main]
java.lang.AssertionError: 820255506 vs 518814720

Is this really data corruption problem and how can I fix it?
I have only one node so nodetool repair won't help.
Thanks.
