> Reporter: Hongshun Wang

> When run e2e test, an error like this occrurs:
> !image-2023-07-25-15-27-37-441.png|width=733,height=115!
>
> The corresponding code:
> {code:java}
> kill_test_watchdog() {
> local watchdog_pid=$(cat $TEST_DATA_DIR/job_watchdog.pid)
> echo "Stopping job timeout watchdog (with pid=$watchdog_pid)"
> kill $watchdog_pid
> }
> internal_run_with_timeout() {
> local timeout_in_seconds="$1"
> local on_failure="$2"
> local command_label="$3"
> local command="${@:4}"
> on_exit kill_test_watchdog
> (
> command_pid=$BASHPID
> (sleep "${timeout_in_seconds}" # set a timeout for this command
> echo "${command_label:-"The command '${command}'"} (pid:
> $command_pid) did not finish after $timeout_in_seconds seconds."
> eval "${on_failure}"
> kill "$command_pid") & watchdog_pid=$!
> echo $watchdog_pid > $TEST_DATA_DIR/job_watchdog.pid
> # invoke
> $command
> )
> }{code}
>
> When {{$command}} completes before the timeout, the watchdog process is
> killed successfully. However, when {{$command}} times out, the watchdog
> process kills {{$command}} and then exits itself, leaving behind an error
> message when trying to kill its own process ID with {{{}kill
> $watchdog_pid{}}}.This error msg "no such process" is hard to understand.
>
> So, I will modify like this with better error message:
>
> {code:java}
> kill_test_watchdog() {
> local watchdog_pid=$(cat $TEST_DATA_DIR/job_watchdog.pid)
> if kill -0 $watchdog_pid > /dev/null 2>&1; then
> echo "Stopping job timeout watchdog (with pid=$watchdog_pid)"
> kill $watchdog_pid
> else
> echo "[ERROR] Test is timeout"
> exit 1
> fi
> } {code}
>
