Hi All,
I just upgraded from Cassandra 1.1.7 to 1.2.3 and im now seeing a lot of the following error
in my output.log, cant find much on the web about it:
ERROR 11:56:01,317 Exception in thread Thread[ReadStage:7236,5,main] java.lang.AssertionError:

I dont know Java and im struggling to identify exactly which query is causing this, is there
a way to trace this back to a specific query?
Any help appreciated.
