How to connect JDBC connectivity to Hbase using JMeter?
Please help here and share some links and drivers so that I can refer them.
Thanks in Advance.
If this is something you really want there is Apache Phoenix project, given you have the driver under JMeter Classpath you should be able to use org.apache.phoenix.jdbc.PhoenixDriver class and URL like jdbc:phoenix:server1,server2:3333
However it might be easier to go for Hadoop/HBase plugin which provides:
HBase Scan Sampler
HBase Rowkey Sampler
and HBase CRUD Sampler
the plugin can be installed using JMeter Plugins Manager

How to integrate Oracle DB/APEX with abinitio.
Scenario : I have a Abinitio code which generates the monthly report. So being database developer i wants to run same code which is in abinitio and generates monthly report. So i am looking for any connector between Abinitio and oracle DB / APEX.
To integrate Oracle with another database you have different options
JDBC (you have to develop this function in JAVA as ETL) (Use a software like Talend or another ETL)
Oracle Link Database (You have to ask your DBA if it's possible)
Expose the info in JSON and make a web service call (Develop a web service in java, node, python, as so on) and consume the json exposed.
If I were you, I would use the option number 3 because It's cleaner option.
If you need more info let me know asap.
Preliminary step: make sure that JDBC drivers is installer and accessible
create DBC file for specify connection to Oracle DBMS.
use m_db for generate DBC template and also for test connection from Shell or GDE
I am trying to connect a Nifi QueryDatabaseTable processor to Salesforce in order to retrieve data to load into a Marklogic data hub. I found a couple of shareware JDBC drivers for Salesforce but have not been able to successfully connect to the SF Connected App endpoint I've been given. Can anyone advise whether this is a good approach for automated data retrieval from SF? Should I be able connect to a SF Connected App URL via JDBC driver like the one at ascendix?
TIA!
I ended up finding a free Salesforce JDBC driver (not the ascendix driver, which did not work for me) that seems to work fine for simple select queries to pull data from a Salesforce Connected App. So, the JDBC approach for this solution works using a Nifi QueryDatabaseTable processor which produces an Avro dataset that is easily split into records and converted to JSON for ingest to MarkLogic.
Yes, the RelierSoft driver works for me, though the 0.4 version (Oct 2019) of the JAR is packaged with an old version of the apache commons.csv library that causes errors for some latest NiFi services, like CSVReader. So, I repackaged it without the old commons.csv library classes to make that service work for me.
I am currently doing an app that loads data into HBase, I chose HBase because the data is not structured and therefore using a column based database is recommended.
Once the data is in HBase I thought of integrating Solr to it but I found little information about the subject and no answer for my question "https://stackoverflow.com/questions/36542936/integrating-solr-to-hbase"
So I wanted to ask how I can query data stored in HBase? Spark Streaming doesn't seem to be made for that ..
Any help please ?
Thanks in advance
Assuming that your question is on how to query data from Hbase.
Apache Phoenix Provides a Sql Wrapper over Hbase.
Hive Hbase Integration Hive also provides a Sql Wrapper over Hbase
Spark Hbase Plugin lets your Apache Spark application interact with Apache HBase.
I am new user to solr,I want to access and search the MYSQL database tables in java applications via solr.i am able to index my table in solr admin interface. Can anyone tell me how to connect and access MYSQL tables in java application so that i can search data fastly ? I was not able to understand tutorials whatever i found.
Solr provides client libraries in java, ruby and other languagues to help you connect to Solr and query it.
Check for the Java library Solrj to connect and query Solr.
If you are using Frameworks with your projects you might want to check for Spring data as well which will help you seamlessly query and transform Solr response.
So you will need to set up an instance of a Solr Server, SOlr will store and indexes from your database using the DataImportHandler.

Solr creates indexes using Lucene, so you have two options, you can use classes from the Lucene jar file or SolrJ to search your indexes.
OR
You can query Solr by sending http requests. I set-up a Java Web Service so you can snatch some of my code if you need to.

I am looking for an example of a project where a SmartGWT Hibernate Datasouce is connected to a Google Cloud SQL database using GAE as the server. I would be surprised to be the first one in this world to have attempted.
We'd recommend using SQLDataSource instead (simpler, faster, more flexible). Google documents appropriate JDBC settings here:
https://developers.google.com/appengine/docs/java/cloud-sql/developers-guide#use_with_lang
SmartGWT documents how to provide JBDC settings to SQLDataSource here:
http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/docs/SqlSettings.html
You would use MySQL as the database type since CloudSQL is MySQL-compatible.
If you choose to use Hibernate, we haven't tried this, but presumably the same JDBC settings can be provided to Hibernate - see Hibernate docs.
