      Description

      Kylin would execute quite a few hadoop command when building cube, such as dfs, set "mapreduce.job.reduces", set "hive.merge.mapredfiles" and more. Some commands are mandatory, and some are optional for better performance.

      Usually in a hadoop cluster, Apache Kylin should be treated as a
      privileged user (instead of a normal user like analyst), which can execute
      necessary hadoop/hdfs/hbase/hive actions (like mkdir, create htable, etc);
      To achieve this, the administrator need do some configurations and
      authorizations.

      What we need do is to compose a document to list these privileges.
