Azure Databricks - Library Installation Fails

I am running a job from a jar file in Azure Databricks. This jar has a dependency on azure-storage-file-share. Previously, there wasn't an issue installing this dependency using Maven within the Databricks UI. Now, I get failure with this error message:
Run result unavailable: job failed with error message Library installation failed for library due to user error for maven { coordinates: "com.azure:azure-storage-file-share:12.16.2" } Error messages: Library installation attempted on the driver node of cluster 0131-144423-r1g81134 and failed. Please refer to the following error message to fix the library or contact Databricks support. Error Code: DRIVER_LIBRARY_INSTALLATION_FAILURE. Error Message: java.util.concurrent.ExecutionException: java.io.FileNotFoundException: File file:/local_disk0/tmp/clusterWideResolutionDir/maven/ivy/jars/io.netty_netty-transport-native-kqueue-4.1.86.Final.jar does not exist
To try to work around this, I manually installed this netty library (and several others) as well. I can see in the logs that it was able to download the jar successfully:
downloading https://maven-central.storage-download.googleapis.com/maven2/io/netty/netty-transport-native-kqueue/4.1.86.Final/netty-transport-native-kqueue-4.1.86.Final-osx-x86_64.jar ... [SUCCESSFUL ] io.netty#netty-transport-native-kqueue;4.1.86.Final!netty-transport-native-kqueue.jar (202ms)
However, it still fails. This is error message is in the same log after the one above:
23/01/31 14:50:09 WARN LibraryState: [Thread 137] Failed to install library maven;azure-storage-file-share;com.azure;12.16.2;; java.util.concurrent.ExecutionException: java.io.FileNotFoundException: File file:/local_disk0/tmp/clusterWideResolutionDir/maven/ivy/jars/io.netty_netty-transport-native-kqueue-4.1.86.Final.jar does not exist

Fatal error: require_once(): Failed opening required 'pre.php' in /usr/share/tuleap/src/www/index.php

I have installed xampp and then tuleap in centos and gave /usr/share/tuleap/src/www as document root in /etc/httpd/conf/httpd.conf
When I hit the url, I am getting the following error:
Warning: require_once(pre.php): failed to open stream: No such file or directory in /usr/share/tuleap/src/www/index.php on line 9
Fatal error: require_once(): Failed opening required 'pre.php' (include_path='.:/opt/lampp/lib/php') in /usr/share/tuleap/src/www/index.php on line 9
I am also seeing that the document root points to /usr/share/tuleap/src/www and pre.php is not in this folder. Instead it is at include/pre.php I am totally confused on this directory structure. I didn't change any code after installing tuleap.
Please let me know how to fix this issue.
Thanks in advance!

OpsCenter Installation error: DNSLookupError: DNS lookup failed

I downloaded the tar.gz file and I'm trying to install Opscenter. I am getting the following error.
ERROR:
Trying to download https://opscenter.datastax.com:443/definitions/5.0.1/version.md5
resulted in following error:
Traceback (most recent call last):
File "build/lib/python2.6/site-packages/opscenterd/Definitions.py", line 133, in getNewHash
DNSLookupError: DNS lookup failed: address 'opscenter.datastax.com' not found: [Errno -2] Name or service not known.
Do I need to have internet access to install Opscenter?
This error should not prevent OpsCenter from working correctly, you just won’t have update information (for cases when you’re running outdated versions of Cassandra or OpsCenter.)
OpsCenter does not require internet connection.
You should be able to configure OpsCenter to not fetch the updated definition files. Refer to OpsCenter configuration properties and look for the [definitions] auto_update property which you can set to False.

How to change Repository RHEL

So, I'm trying to change my Repositorys in RHEL but I allways get the following message and have NO IDEA what it means.
Loaded plugins: product-id, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

You can create your own repository if you have os image.
Mount os image at some folder say /var/rhel-repo using
mount -o loop /path/to/os_image /var/rhel-repo
create repo file in /etc/yum.repos.d/customrepo as
[customrepo]
name=Custom Repository
baseurl=file:///var/customrepo
enabled=1
gpgcheck=0
save file.Then
yum clean all
Configuration of repositories are in /etc/yum.repos.d/ folder on RHEL like systems.
Looking on your error message:
you don't have active Subscription with RHEL, so you cant access any RHEL repositories. Use subscription-manager to register
every repository you are trying to connect to, is unreachable or you are getting timeout. Check your internet configuration / connection.
