Thank you every one it is working fine.

I was watching jconsole behavior...can tell me where exactly I can
find "  *RecentHitRates"
:
*Tuning for Optimal Caching:
Here they have given one example of that  *
http://www.datastax.com/docs/0.8/operations/cache_tuning#configuring-key-and-row-caches
* *RecentHitRates...  *In my jconsole within MBean I am unable to find
that one.
what is the value of long[36] and long[90].  From Jconsole attributes
how can I find the  *performance of the casssandra while stress testing?
Thank You

It's in the source distribution under tools/stress see the instructions in the 
README file and then look at the command line help (bin/stress --help).

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..

Re: Stress test using Java-based stress utility

[aaron morton]

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. 

Cheers

Have you checked the logs on the nodes to see if there are any
errors?
