Hi, We have tested the benchmark on a similar setup and we didn't encounter any problems regarding the network. There are two possibles that I can think of:
1) There are Iptable rules (e.g., firewall) that prevent the connection. You can simply flush or clear all the iptable rules. 2) There is an empty character right after you specify the ip of the server machine in settings_load.dat file. Removing that character would solve the problem. To remove the character, please open settings_load.dat file with vim, move the cursor to the end of the ip address (I guess it is 127.16.19.16 in your case) and use 'x' key to remove all hidden characters. If these don't help, please send us the exact settings_load.dat file and the load command. Good luck!

And there was a problem that bored me for several days. I am in desperate need of your help! The problem is as follows. I used two virtual boxes to run the benchmark. One box is for YCSB and the other for Cassandra. And both boxes have their own static ip addresses and I can ping each other without problems. I have installed the related software successfully and made sure the Cassandra can start up and also I generated the dataset. And I set the cassandra ip address correctly in the Settings_load.dat under YCSB. But when I ran the YCSB, the operations were all 0 no matter how long I waited. I thought it was not right, for I made a successful practice on just one single virtual box (YCSB and Cassandra both setup on it). More info about the details about the softwares: 1 OS: CentOS 6.2 (later I tried CentOS 5.5 and the problem still exsited) 2 Virtual box ip addresses: 172.16.19.16 for Cassandra and 172.16.19.15 for YCSB 3 Cassandra version: 0.7.3 4 YCSB version: 0.1.3 5 JAVA version: 1.7.0_09 6 Ant version: 1.8.4 Please HELP! ---------------------------------- Thanks and Regards, Tracy Zou
