I am trying to create a form and using servlets connect with hive´s tables. But I have some doubts:
Is Hive server installed in cloudera quickstart?
It is necessary other server like Tomcat for the servlet?
Must I have the libraries in the IDE? Or also in other place?
Is possible with a form launch a servlet and display the data in the navigator on cloudera quickstart?
JDBC must be installed in my local host or also in the virtual machine?
Where do I declare the XML?
I would suggest using HiveServer JDBC,
Write your web application and deploy where ever you want to just use Hive JDBC drivers to connect and query Hive.
Here is more info Hive JDBC

Has anyone successfully created a JDBC Resource connection for the Snowflake database? I have a specific case, where I would like to connect directly, not through Snowflake plugin. I am stuck at database driver selection. Can't import snowflake-jdbc-3.13.24.jar to choose it in dropdown menu.
I already tried this, but it doesn't work:
https://docs.tibco.com/pub/activematrix_businessworks/6.2.1/doc/html/GUID-DF12A927-F788-46DC-ABA1-0A1BA797DE2F.html
I never worked with Snowflakes but the BusinessWorks 6.6 documentation provides updated explanations on how to set-up a custom JDBC driver in the BusinessWorks environment, you can check it at the following URL :

I am trying to export data from Kafka to Oracle db. I've searched related questions and web but could not understand that we need a platform (confluent etc.. ) or not. I'd been read the link below but it's not clear enough.
https://docs.confluent.io/3.2.2/connect/connect-jdbc/docs/sink_connector.html
So, what we actually need to export data without 3rd party platform? Thanks in advance.
It's not clear what you mean by "third-party" here
What you linked to is Kafka Connect, which is Apache 2.0 Licensed and open source.
Kafka Connect is a plugin ecosystem, you install connectors individually, written by anyone, or write your own, just like any other Java dependency (i.e. a third-party)
The JDBC connector just happens to be maintained by Confluent. and you can configure the Confluent Hub CLI
to install within any Kafka Connect distribution (or use Kafka Connect Docker images from Confluent)
Alternatively, you use Apache Spark, Flink, Nifi, and many other Kafka Consumer libraries to read data and then start an Oracle transaction per record batch
Or you can explore non-JVM kafka libraries as well and use a language you're more familiar with doing Oracle operations with
I'm trying to connect my postgresXL database with jmeter, where do i find postgresXl jdbc driver and how to connect it to jmeter?
I've tried postgreSQL jdbc driver but it does not work for me.
Postgres is not a Java application. It is a database compiled to native executable code. It does not run in a Java JVM. You can not use JVM monitoring tools like Jmeter with it.
I want to expose Oracle database data with an Odata endpoint.I tried using JayData server on node.js but it currently supports only mongo db but not oracle.So before I start trying connecting Oracle with Apache Olingo I would like to know if someone has already been this path.Please advise
