      Description

      A Webserver:

      1. cannot serve/convert a lot of data
      2. cannot pull the query statuses continuously and download / cache the first part of results before releasing the query resources
      3. resultsetl conversion takes minutes to be done and give a "hanging" feeling to the user

      We probably need a task server to free it and scale downloads.

      FI: Beelines has these options https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-BeelineCommandOptions

      Priority is on SQL (Hive, Impala).
