I am new to hbase and I got a few questions: 1. tables are divided into regions and allocated to region servers. what is the allocation policy? 2. From my understanding, if a region server get requests for data on the same host, for data locality, all requests will be served by the local host, right? Unless the max connection for the data node is reached. If this is the case, for random read request, can requests access the data simultaneously? 3. When doing a update, e.g. add a new version to a column, how the system lock the record?
