Index memory quota on data nodes

When using MDS, if I have exclusive nodes for data and exclusive nodes for index, can I set the indexMemoryQuota to 0MB on the data nodes so the memoryQuota can be set to all available RAM in the machine? Can I do the same on index nodes by setting memoryQuota to 0MB and indexMemoryQuota to all available RAM in the machine? Also, If I do this on the data nodes, will I be able to run MapReduce Views?

Thanks
