> DataXceiver#run() just log InvalidToken exception as an error.
> When client has an expired token and just refetch a new token, the DN log
> will has an error like below:
> {noformat}

> This is not a server error and the DataXceiver#checkAccess() has already
> loged the InvalidToken as a warning.
> A simple fix by catching the InvalidToken exception in DataXceiver#run(),
> only keeping the warning logged by DataXceiver#checkAccess() in the DN log.
