Hello all, We are getting ready to install hadoop cluster(16 data nodes) about 20TB usable space after 3X replication. We plan to keep all the metastore that is required by hive, ooize, etc etc .. external to the cluster. I am trying to find any specs/requirements for this metastore. This will be a Mysql 5.7 but i cant seem to find any requirement as in how much storage is required for this mysql database, CPU, memory etc..
What is the community doing for such a setup where the metastore is external and you are using mysql, how fast is it growing and what hardware do you have for these ?
