Hello aaron,
I hope you had a nice flight.
>Any information on how you are using cassandra, does the zero columns no
row delete idea sound like something you are doing ?
I do not know what I could do, but we use an old versions of phpcassa
(0.8.a.2) that are not explictly compatible with cassand
On a plane and cannot check jira but…

Thanks Robert,
you are right, I upgraded to 2.0.1 and don't fix the problem, 2 of 3 nodes
raise the same error after 30 minutes.
I will try to create a new cluster 1.2 and copy data, can you tell me
please the best pratice to do this, do i have to use sstable2json /
json2sstable or other method.

Hi all,
We have recently run in production a new cluster C* 2.0.0 with 3 nodes RF 3.
After 7 days, we seen on log this error on one node :
ERROR [FlushWriter:216] 2013-10-07 07:11:46,538 CassandraDaemon.java (line
186) Exception in thread Thread[FlushWriter:216,5,main]
java.lang.AssertionError
To note: I still have the problem in before beta 1.1 custom build that
seems to have the fix. I am going to upgrade to 1.1 beta and check if
problem will go away and will file a bug if problem still exists.
BTW: It would be great for cassandra to exit on any fatal errors, like
assertion problems
Fixed in 1.0.3
