Review Comment:
@koodin9, you can get a token like
````
String tokenSig = MetastoreConf.getVar(conf, ConfVars.TOKEN_SIGNATURE);
tokenStrForm = SecurityUtils.getTokenStrForm(tokenSig);
````
do you know if renew helps here?
````
if (tokenStrForm != null) {
renewDelegationToken(tokenStrForm);
}
````
I could only imagine that the issue is caused by the expired TGT and not the
HMS service restart per se
