hive - Do I really need hiveserver2? -


i using hive v.0.13.

i confuse function of hiveserver2. if data in hdfs, have tried use "hive" cli create external table without having hiveserver2 started hence question correct? or did miss out anything? if yes what, if not when need hiveserver2?

starting in hive 0.13, hiveserver2 provides support sending thrift rpc messages on http transport (hive-4752). particularly useful support proxying intermediary between client , server (for example, load balancing or security reasons). currently, can run hiveserver2 in either tcp mode or http mode, not in both. useful.
