Hi All, I have just started to use virtual nodes. I set the number of nodes to 256 as recommended.
The problem that I have is when I run a mapreduce job it creates node * 256 mappers. It creates node * 256 splits. this effects the performance since the range queries have a lot of overhead. Any suggestion to improve the performance? It seems like I need to lower the number of virtual nodes. Best Regards, Cem
