Any updates on this issue?

[vdesikanvmware]

Is there a fix planned for this issue?

[krizh1990]

Adding this line in headers of testdriver.go fixed the issue

_ "k8s.io/client-go/plugin/pkg/client/auth/gcp"

[vipinms2]

I have added "k8s.io/client-go/plugin/pkg/client/auth/gcp" in the header as

import (
        "k8s.io/client-go/plugin/pkg/client/auth/gcp"
        "bytes"
        "io/ioutil"
        "k-bench/manager"
        "k8s.io/client-go/dynamic"
        "reflect"
        "strings"
        "sync"
        "time"

        log "github.com/sirupsen/logrus"
        metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
        "k8s.io/client-go/kubernetes"
        restclient "k8s.io/client-go/rest"
        //"k8s.io/client-go/tools/clientcmd"
        "k-bench/perf_util"
        "os"
        "os/exec"
        "path/filepath"
)

I am facing the below error while performing ./run.sh -t dp_fio:
