And yes, I plan to run some MR jobs against the data. Sort of health checks of the data. But this jobs are of low priority and can run when the other parts are not needed. > If this cluster is dedicated to your application and you have enough > IO capacity to support all application needs on the cluster, I see no > reason to run two clusters. okay. > The reason we recommend against running mixed-workload clusters is those > additional tasks compete for the resources hbase needs to meet its online > SLAs. okay. So, if I understand correctly, you recommend to put it together. I will do checks to test the io capacity. If hdfs gets do not kill the hbase performance, I go with a combinded cluster. Thanks a lot, Wilm
