Create impala table and add data using java

问题:

I am trying to create an impala table and add data into it using java.

1.) How should I create connection for impala?

2.) Can I create an impala table directly or should I create a hive table and access it using impala?

A java program or code snippets will help.

You could use the impala jdbc driver.

Refer the following link , this has a sample code for the impala connection using the jdbc driver.

For creating a table in impala you could pass it as a query, neednot do it in hive. In case you add/create a table in hive then you need to invalidate metadata in impala so as to reflect the table details in impala.
