How to deploy multiple Spring boot applications with external configurations on the same Tomcat?

When I want to deploy multiple Spring-Boot applications on the same tomcat I face multiple problems.
1) Both applications have to run independent while sharing the same tomcat. When deploying two Spring-Boot application on the same tomcat I get the following Exception:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

2) I need to provide external configurations for both applications and it needs to be clear that each application uses the right configuration.

1) When two Spring-Boot applications run on the same tomcat you will normally face the issue that the instantiation of a datasource might fail, because an instance with the same name already exists. This is the exception you described in your question.
This can be solved by adding a unique name to each Spring-Boot application e.g. in the
application.yml
spring:
application:
name: application-name-1
jmx:
default-domain: application-name-1
2) Providing an external configuration for each Spring-Boot application can be done by tomcat context configurations for every application individually. Assuming that all applications are deployed as .war e.g. app1.war, app2.war we need to configure the context for both applications as the following:
create the following files (and directories if missing)
tomcat-base-dir
/conf
/catalina
/localhost #must be the same as specified in the Host tag in the server.xml
app1.xml #must have the same name as the .war application file
app2.xml
Content for the app1.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- docBase must contain be the name of the application to be configured -->
<Context docBase="app1.war">
<Parameter name="spring.config.location" value="${catalina.base}/conf/app1.yml" />
</Context>
This will configure the application app1.war to use the file app1.yml for configuration. Do the same for app2. The actual configuration file app1.yml can be located at any path specified in the value.

#user3855589, you probably have two different versions of commons-logging: one in your war and one in tomcat. You should put the one in your war in provided scope (if you are using maven) or just exclude it from your war, and than deploy it in Tomcat. Check out a similar error.

Kindly help to solve this
Update 1:-
Tried the following to connect My application on Azure VM with ADLS:-
Added azure-data-lake-store-sdk in lib
I have followed this Service-to-service authentication to create application in Azure Active Directory .
I have also assigned the Azure AD application to the ADLS account root directory.
Root directory -> /clusters/myapp
Updated core-site.xml based on values from above documentation.

Using following jars in my project:-
azure-data-lake-store-sdk-2.1.4.jar
commons-cli-1.2.jar
commons-configuration-1.6.jar
hadoop-auth-2.7.1.jar
hadoop-azure-datalake-3.0.0-alpha1.jar
hadoop-common-2.5-SNAPSHOT.jar
hadoop-common-2.7.1.jar
hadoop-hdfs-2.7.3.jar
hadoop-hdp2-2.5-SNAPSHOT.jar
Clarifications:-
My intention is to connect My application on Azure VM with DataLake Store with out need of HDInsight Cluster. Is that possible ? If so what steps should I need to follow ? What are the configuration needs to be present in core-site.xml ?
File preview fails with AccessControlException error in ADLS
Login the HDInsight cluster which is associated to the Data Lake Store using ssh command - ssh [user]#[cluster2]-ssh.azurehdinsight.net
Copy a file to the cluster using the wget command - wget http://www.sample-videos.com/csv/Sample-Spreadsheet-10-rows.csv
Create a new folder in your Data Lake Store account
Now upload a file using PUT command
hdfs dfs -put Sample-Spreadsheet-10-rows.csv adl://dev2.azuredatalakestore.net/new
View the file in the Azure Portal
Actual Result: The file is uploaded and shows in the Azure Portal. But, file preview is broken and I see the below error
AccessControlException
OPEN failed with error 0x83090aa2 (Forbidden. ACL verification failed. Either the resource does not exist or the user is not authorized to perform the requested operation.). [4f97235c-0852-44c8-a8d4-cbe190ffdb34]
How to solve this issue ?

Firstly, we really do not recommend that you use the swebhdfs path. As called out in Arsen’s blog, the adl client is much more performant. Here are directions for configuring the adl filesystem:
Hadoop Azure Data Lake Support
For your specific error, it looks like the mkdir is invoked on the local file system as shown by the "file:" in the output of the mkdir command.
To solve the error, follow the steps mentioned in Arsen’s blog. After configuration, run hdfs command on the swebhdfs path like
bin\hadoop> fs -ls swebhdfs://avdatalake2.azuredatalakestore.net:443/
One more thing: Since posting that blog, Azure Data Lake now has full support for the Java SDK. Here is an article that describes how to use the Java SDK to perform basic file operations:
Get started with Azure Data Lake Store using Java
-- Cathy

The easiest way to connect to ADLS is to use the Java SDK that Cathy mentioned in her response.
Get started with Azure Data Lake Store using Java
In your example why are you trying to connect from your Azure VM with the data lake store using the Hadoop client? Using the Hadoop client is a more convoluted way to achieve the seemingly simple scenario of connecting from your app on an Azure VM to ADLS.
The Hadoop client is typically what people do to connect existing Hadoop clusters to ADLS. I have a feeling that is not what you are trying to do. Let us know if this is not the case.

Openshift Unable to locate persistence units

I'm developing Hibernate JPA persistance web application, with my persistence.xml in src/main/resources/META-INF/persistence.xml (in war file it's in WEB-INF/classes/META-INF). It all works well on local Tomcat server, but when put on Openshift JBoss EWS, getting this message on startup:

and has two persistence units in it. I alse deleted hibernate.cfg.xml, both things suggested in other SO answers. Anyone know what I'm doing wrong here?

Got it.
The problem was I used Persistence.createEntityManagerFactory("unit") to create EntityManagerFactory and injected it in other Spring beans.
Now I put
<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="unit" />
</bean>
directly in applicationContext.xml.
Still doesn't explain what was wrong with previous approach, but it works.

Unable to locate persistence units

In IntelliJ Idea I created a project with JPA 2.1 and hibernate 4.3.10 final. After I created a datasource (Test connection : Success) I generated persistence mapping from database. Project compiles without error. When I tried to test in JPA Console with a simple Select * query, it returns following exception:

Can someone tell me how to fix this error? I was searching and reading for about 10 hours without success
EDIT
If I try to deploy the app on wildfly without creating entities from database it will deploy the app. However, if I try to deploy the app after the entities are created i get the following error:

I think your Jars (JPA / Hibernate) are probably older.
What Jars are you using?
Usually when you download something like Hibernate, they allow you to download sample projects which have the example of such persistence.xml and other files.
Update
Maybe the app isn't picking up the expected persistence.xml file?
Try to add some obviously incorrect, invalid text in your persistence.xml file. This way, the exception will printed out with the complete name of the persitence.xml that is being looked at.

I think you have to change your persistence.xml
The following line
<property name = "hbm2ddl.auto" value = "update" />
must probably be changed to
<property name = "hibernate.hbm2ddl.auto" value = "update" />
Then I suppose you do not have any password in your database
<property name = "hibernate.connection.password" value = "?" />
Otherwise, I see nothing strange.
