@Tomomichi Hirano ya you can initially go with enabling ranger at hiveserver2 level for now,hiveserver2 will expect that you have read/write permission for hive user on file/folder on hdfs, Additionally, if you install ranger plugin for HDFS then it will be good for you so that you need not mess with hdfs acls and with ranger you can manage at a single place.

@Triffids G if you have hive installed on the sandbox you can copy /usr/hdp/2.6.0.3-8/hive/lib/parquet-hadoop-bundle-1.8.1.jar and paste it to /usr/hdp/2.6.0.3-8/hadoop/lib and try running the job again and let me know how it goes.

@Tomomichi Hirano LLAP cache data for several queries running on it so doAs is not supported in LLAP, every query run on LLAP run as hive user instead of the user who submitted the query. to get a fine grain control over accessibility you can user Ranger security policies along with hive.server2.enable.doAs=false

no need to store the result in RDBMS, these libraries are javascript library, you can pull the result using java jdbc program https://github.com/rajkrrsingh/HiveServer2JDBCSample, set in some variable and plot using these libraries.

@heta desai you can pull the query result from hive using hive-jdbc and plot using d3js (https://d3js.org/) or c3js (http://c3js.org/examples.html)
