-----------------------------------
Summary: Make Zeppelin be easier for normal users by generating
code reading data and automatically run SQL command
Key: ZEPPELIN-816
URL: https://issues.apache.org/jira/browse/ZEPPELIN-816
Project: Zeppelin
Issue Type: New Feature
Components: GUI
Affects Versions: 0.6.0
Reporter: Le Van Duc
Currently, Zeppelin visualization ability is focus mainly on developers who
know code in Scala Spark and SQL. I want to make Zeppelin easier for normal
users who want to use Zeppelin visualization to analysis their data but have
little coding knowledge.
I will focus on analysing CSV files on Spark (or another structured file such
as logs) which normal users want most to analysis and view visualization.
I will create a function on a Zeppelin notebook to let the users choose CSV
file to upload then I will read all fields in file to show for users to select:
which fields they want to analysis, what is the name of fields they want to
display, which data type of the fields (in some basic and simple types such as:
String, Integer, Double, DateTime, Boolean). Then this function will upload
this file to server and generates code to process file in Scala Spark. And then
I will use Zeppelin REST API to create new paragraph (available from v0.6.0)
and automatically run. After that I will have table in Spark environment and I
will create the basic SQL command: select * from <table_name> then using
Zeppelin pivot table function to view data.
As a result, the users will not have to code any more to have data to be
analysed and visualized. If the users have code experience, they will use the
generated code to make more complex SQL commands.
By the way, I want to add more options to Zeppelin REST API such as:
- When run a paragraph, you can choose which chart will be displayed first
rather than table as default.
