Hi, I am confused with some thing in HBase.
1. All data is stored in HDFS. Data is served to clients by HRegionServers. Is it allowed that the tablet T is on machine A, and served by a HRegionServers running on machine B? What information does the META table maintain? The map from T to the physical address in machine A, or the map from T to which machine serves it, for example, machine B? 2. Similar to Bigtable paper, what does the tablet location(section 5.1) stand for? Is it the map from the tablet id to physical address, or the map from the tablet to which machine serves it? thanks -- Bin YANG Department of Computer Science and Engineering Fudan University Shanghai, P.
