Hello all, I have seen that the HBase project provides lot of features for multi-tenancy like security, isolation in terms of resources, namespaces etc. I saw some examples of companies like Bloomberg and Yahoo using those features in production (HBaseCon videos).
It would be helpful if anyone can share the scale at which those clusters are being operated at? I would also like to generally know how's the operational burden for those clusters? In general, what is preferred, running separate clusters for various tenants (assume that infrastructure is really flexible) vs running a bigger single-tenant cluster (that requires tuning of various config resource isolation parameters)? I know that there is no *best* approach, but what are the general guidelines? Rahul
