Hi bro,
I am new in spark application develop, I need develop two
app running on spark cluster.
Now I have some arguments for the application.
I can pass them as the program arguments when spark-submit,
I want to find a new way.
I have some arguments such as ,jdbc url, elastic search
nodes , kafka group id,
So I want to know whether there is a best practices to do
this.
Can I read this from one custom properties file?
Another similar question is that, I will read some rules to
analysis data,
Now I store the rules in mysql, before I use it ,I read it
from mysql.
Is there better way to do this?
Thanks in advance.
Best Regards,
Evan Yao
