a problem in Splunk UBA Installation

Nrsch — Sun, 07 Sep 2025 07:26:58 GMT

Hi, I am installing Splunk UBA 5.4.2 on my laptop in a virtual machine (RHEL 8.8) for testing. I followed the installation steps up to “Install Splunk UBA: Run the setup script /opt/caspida/bin/Caspida setup” as described here: Splunk UBA 5.4.2 Single Server Installation Guide.

The setup runs for a few minutes, but then I receive the following error:

waiting on impala containerized service to come up
Running CaspidaCleanup, resetting rules
Cleaning up node uba.mysplunk
checking if zookeeper is reachable at: uba.mysplunk:2181

impala jdbc server at:jdbc:impala://uba.mysplunk:21050/;auth=noSasl not reachable, aborting

Could someone help me understand why this error occurs?

Hi @Nrsch ,

if you open a case to Splunk Support, they answer that UBA must be installed by Splunk PS to be certified.

For my experience I hint to check the versions of the operative system, checking all the installed packets: I had a Red Hat 8.8 installation where some pachets were in 8.9 and we received many installation errors.

Ciao.

@Nrsch

I agree with @gcusello , Splunk UBA is highly dependent on both the OS version and the packages installed. When setting up UBA on a laptop, especially in a virtual machine, it is essential to verify that all system requirements(especially resource allocation) are satisfied before starting the installation process. Most installation packages provided with UBA include automated checks to ensure your system meets these requirements before proceeding.

You can refer below,
