Troubleshooting Sisense validator [Linux]
Step-by-Step Guide:
In case the Validator is failing, we can perform some adjustments and review its process from the pod itself to verify what exactly went wrong.
As the Validator pod is launched by its job, it is designed to be stopped after completion, whether it was successful or not.
So, in order to proceed, we will need to copy the existing job and launch its test duplicate, but with adding ‘sleep’ option added so it would remain running even after completion. We will also need to get rid of auto-generated values filled during the original job creation.
You can run the following command that will:
- Search for the latest Validator job
- Remove unneeded values
- Re-launch its copy with “test” name and “sleep” option
===============
kubectl -n sisense get job $(kubectl -n sisense get jobs -l app.kubernetes.io/name=validator -o json | jq -r '.items | sort_by(.metadata.creationTimestamp) | last | .metadata.name') -o json | \
jq 'del(
.metadata.creationTimestamp,
.metadata.generation,
.metadata.resourceVersion,
.metadata.uid,
.spec.selector,
.status,
.spec.template.metadata.labels["controller-uid"],
.spec.template.metadata.labels["batch.kubernetes.io/controller-uid"]
)
| .metadata.name = "validator-test"
| .spec.template.metadata.labels["batch.kubernetes.io/job-name"] = "validator-test"
| .spec.template.metadata.labels["job-name"] = "validator-test"
| .spec.template.spec.containers[0].command[2] |= gsub("# sleep 6h"; "sleep 6h")' | kubectl apply -f -
===============
After running this command, the new job and its pod with the name validator-test-xxx will be created and will remain in the running state for 6 hours.
For further troubleshooting, follow the steps below:
- Exec into the pod:
kubectl -n sisense exec -it $(kubectl -n sisense get pod | grep validator-test | awk '{print $1}') -- bash - Execute run.sh script with ‘bash -x’ (will show detailed process of script execution):
bash -x ./run.sh - Observe the results that will help to better understand the nature of the issue
After troubleshooting is done, feel free to delete the test Validator job:
=========
kubectl -n sisense delete job validator-test
=========
