Hi, I have three node cluster with RF=1 (only one Datacenter) with following size:
Datacenter: DC1 =============== Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack UN <IP1> 4.02 GB 1 33.3% <ID1> RAC1 UN <IP2> 4.05 GB 1 33.3% <ID2> RAC2 UN <IP3> 4.05 GB 1 33.3% <ID3> RAC3 I have created different tables and my test application reads/writes with CL=QUORUM. Under load I found that my one node is taking more resources (double CPU) than the other two. I have also verified that there is no other process causing this problem. My hardware configuration on all nodes is same around Linux + 64-bit + 24 core + 64GB + 1TB My Cassandra version is 2.0 and JDK 1.7 Jaydeep
