HDP 2.3.2 on Hortonworks Sandbox, Windows OS, Hive Visualization in general.
We can create charts from Hive tables using the Visualization tab on Hive Query Editor->Visualization, on the HortonWorks Hadoop Ambari Web Interface. The 'data explorer' tab and the 'advanced visualization' allows us to create slices of the data
Currently, the visualizations/reports created under the 'Visualization' tab cannot be saved.
I would like to request the following features to be added to Hive Visualization. In my opinion the following features will boost product adoption as reporting is a critical component of data-centric environment.
1. Ability to SAVE the HIVE visualizations
Users should be allowed to save the visualizations or reports created through the 'data explorer' and 'Advanced visualization' features.
2. Ability to SHARE the saved HIVE visualizations or reports
After the visualizations or reports saved users should be able to share the reports with other users through URL access.
3. Securing the saved visualizations/reports
It is important to secure the saved reports.
The following reporting 'roles' may be considered for controlling access to the reports and to manage the reports:
(3.1) Report Administrator: The 'Report Administrator' administers(backs-up reporting metadata, restores reports and metadata, will do performance tuning, provide access rights, creates reporting roles, maintains and manages reporting system wide configurations etc) of the overall reporting environment.
(3.2) Report Publisher: The 'Report Publisher' role is created by the 'Report Administrator'. The publisher would be responsible for creating reports or visualizations for the 'Report Browsers'. The report publishers would be able to alter the report metadata of reports they have access to.
(3.3) Report Browser : The 'Report Administrator' and the 'Report Publisher' should be allowed to create the 'Report Browser' role. The 'Report Browser' browses or consumes the reports.
All these roles should be available by default (template) , custom roles may be derived from the these roles.
4. Emailing reports
Report Publishers or Report Administrators should have the ability to schedule automated notification the report consumers that the 'reports' have been updated after scheduled data refresh executed successfully, this can be done by simply emailing a hyperlink of the specific reports or by sending an SMS (Short Messaging Service) to a mobile device. Alternatively, 'Report Browsers' should be able to 'Subscribe' to the reports to be delivered to them at a scheduled interval ( hourly, daily, weekly, monthly, quarterly or yearly)
5. Exporting reports
Once the reports are created or saved the users should be able to export the reports to one of the following formats:
5.1 PDF (Portable Document Format)
5.2 Microsoft Excel ( .xls or .xlsx extension)
5.3 LibreOffice or OpenOffice (.ODS) format.
Dashboards contain multiple reports. Once the visualizations are saved, users should be able to create dashboards using the saved reports. Example: Let's assume that we are able to save two separate visualizations or reports. Report 'Monthly Sales' consists of 'sales by month' and the report 'Sales by state' consists of 'Sales by each state'. Users should be able to create a sales dashboard 'Sales Dashboard' comprising of both the reports. The ability to display separate visualizations into one dashboard is very useful as it allows re-usability, effective for decision making, saves time and improves analyst productivity.
A 'Dashboard' tab may be added to the Hive->Query Window web interface.
7. Report execution statistics
There should be a repository to log every report execution. The log table/file should store the unique execution identifier, date and time the report or the dashboard was executed, duration for rending the report in seconds, the user who executed the report, error message if any, report path, calling application name etc.
8. Automated report documentation
Most reports in the corporate environment suffers from lack of documentation. The report documentation should be created automatically. The following basic information should be available in the documentation for each report or visualization.
(8.1) Created by user identifier
(8.2) Created on
(8.3) Report description
(8.4) Report fields and data type for each field
(8.5) Description of or each field
(8.6) Report update date
(8.7) Report updated by
(8.8) Report update comments

Thanks for your help and consideration in advance.
