Current and expected behavior

I want to override livenessProbe because of some memory issues. This is what i want it to be

workers:
  podOverrides:
      spec:
        containers:
        - name: trino
          livenessProbe:
            exec:
              command:
                - /bin/sh
                - -c
                - |
                  #!/bin/sh
                  mem_total=$(grep MemTotal /proc/meminfo | awk '{print $2}')
                  mem_available=$(grep MemAvailable /proc/meminfo | awk '{print $2}')
                  used_percent=$(( (100 * (mem_total - mem_available)) / mem_total ))
                  echo "Node memory usage: ${used_percent}%"
                  if [ "$used_percent" -gt 94 ]; then
                    echo "Node memory usage above 94% — failing liveness probe."
                    exit 1
                  fi

                  # TCP socket check (simulate original)
                  timeout 2 bash -c 'cat < /dev/null > /dev/tcp/127.0.0.1/8080' || exit 1
            periodSeconds: 30
            failureThreshold: 2
            timeoutSeconds: 10

but i get this error in message in my trino worker statefulset:

create Pod trino-coac-worker-default-0 in StatefulSet trino-coac-worker-default failed error: Pod "trino-coac-worker-default-0" is invalid: spec.containers[0].livenessProbe.tcpSocket: Forbidden: may not specify more than 1 handler type

looks like it doesn't really override the livenessProbe as the tcpSocket field still exists?

Would you like to work on fixing this bug?

None

Start by reproducing the StatefulSet validation error with the shown workers.podOverrides configuration and inspect how the Trino liveness probe is merged. Done means an exec-based liveness probe can replace the existing tcpSocket handler without Kubernetes rejecting the generated Pod.
