Re: Stress test using Java-based stress utility
Have you checked the logs on the nodes to see if there are any errors?

Re: Stress test using Java-based stress utility
UnavailableException is raised server side when there is less than CL nodes UP when the request starts. It seems odd to get it in this case because the default replication factor used by stress test is 1. How many nodes do you have and have you made any changes to the RF ? Also check the server side logs as Kirk says.

Re: Stress test using Java-based stress utility
Running only one node. I dnt think it is coming for the replication factor... I will try to sort this out Any other suggestions from your side is always be helpful.. :) Thank you On 22 July 2011 14:36, aaron morton aa...@thelastpickle.com wrote: UnavailableException is raised server side when there is less than CL nodes UP when the request starts.
