----------------------------------------
Summary: Document for Hive/HBase/Hadoop permission required
Key: KYLIN-1938
URL: https://issues.apache.org/jira/browse/KYLIN-1938
Project: Kylin
Issue Type: Improvement
Components: Documentation
Affects Versions: v1.5.3
Reporter: Billy(Yiming) Liu
Priority: Minor
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.
