Currently, we are using druid in our application using the Zapr java client but we do not have a username and password in Druid.
Now in another environment druid is having username and password. We are trying to move the code to this environment (secured druid), but not getting any example to connect to druid using Zapr Java client using username and password.
Looking for quick help .... Thanks in advance !!!

I want to connect to the heroku postgres database I have set up using spring boot java. But before that I wanted to try and connect using pgAdmin 4. When I tried this I got an error saying the authentication for the 'username' had failed.
Then I started adding the database to my application.proporties file in spring boot to test it there. I got the samen error message.
This is the error message I got in spring boot: org.postgresql.util.PSQLException: FATAL: password authentication failed for user "username".
I then even tried it in DBeaver. But still the same error.
heroku postgres credentials
application.properties in spring boot java
I checked multiple times if the password and username are the same. I really don't know what to do now, because I can't find any documantation on the heroku website
I'm NO EXPERT but I did have the same problem. I think I fixed it on the page with fields for Host, Port, Maintenance database, Username, Password, ... and then by toggling "save password."
I'm developing a Java Spring boot application with MongoDb database (MongoDB Atlas) and trying to generate reports from backend with Jasper reporting services. I have followed several tutorials to do that. But all of them show how to connect to a local database. Since I'm using MongoDB Atlas I'm wondering how to give Mongo URI while setting up the Data Adapter (See image)
If anyone knows a better approach to generate reports without using Japer reporting, please mention that as well. Thanks in advance!
You need to have mongodb atlas properly setup before you can connect to it.
First click on Database Access under Security in mongo atlas dashboard and create a new user
Then click on Network Access again under Security and whitelist your IP. The following image allows anyone to connect to the db
Finally, go to your cluster and click connect and you will be presented the following dialog. Copy the connection string from it and paste it into your jaspersoft connected interface.
Make sure you replace the <password> with the password of the user created above
That should work!
UPDATE: here is a screenshot of successful connection to jasperreport studio
DB2 is our Application DB and we are connecting from our application using the DB2 libraries.
However, we store the credentials in an encrypted format and use that for connecting.
If DB2 has an option to connect using a trusted user (like Informix), we could remove the password stored, though it is encrypted.
Anyone knows, is it possible with DB2?
Any help is much appreciated.
Thanks
You may try the Client authentication method or Kerberos Authentication.
Authentication methods for servers.
Kerberos authentication.
I am trying to move my data in MongoDB to Redshift using AWS Glue. To do this, I am trying to add a connection to MongoDB. My MongoDB setup does not have credentials configured. But the Username and Password fields in the Add Connection page are mandatory. Test Connection fails on giving dummy values as they will be considered during the authentication process. Would appreciate any help in this regard.
To be upfront I haven't tried this myself, but to remove the requirement for Username and Password is easy.
Basically in the Migration Setup Wizard in the "Authentication mode" drop-down box select "none". Default value is "password, where the username and password is mandatory.
Hope that assist.
I am trying to connect the spark to tableau, I had installed Simba ODBC driver for 64bit, but I am facing issues while connrecting to spark.
ERROR:
Unable to connect to the ODBC Data Source. Check that the necessary drivers are installed and that the connection properties are valid.
[Simba][ODBC] (10000) General error: Unexpected exception has been caught.
In some doc, I saw that tableau requires some special license key. Can you please explain it
Basically spark works with the hive but with difference engine(algorithm for fetching data)
so initially to connect spark from tableau we need to install ODBC Hive drivers then spark driver.
Hive Driver:
http://www.tableau.com/support/drivers
Spark driver :
https://databricks.com/spark/odbc-driver-download
while installing spark on your cluster we need to configure thrift server with the hive server and need to give new port address.
you can go through using link to install spark in ambari :
http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.4/bk_spark-guide/content/ch_installing-spark.html
And the respective port address need to be specified in tableau while connecting.
If your Cluster is secured with user name and password we need to specify the Authentication as "USERNAME AND PASSWORD" and need to give credentials there..
Even though if it raises error, then look into below areas:
An incorrect port and/or service defined in the connection
Web Proxy or Firewall settings are blocking connection from Tableau Desktop
The data server is not started.
