Summary: Update UGI#spawnAutoRenewalThreadForUserCreds to reduce
indentation
Key: HADOOP-13641
URL: https://issues.apache.org/jira/browse/HADOOP-13641
Project: Hadoop Common
Issue Type: Improvement
Reporter: Xiao Chen
Priority: Minor
>From [~drankye]'s comment in HADOOP-13590:

{code}

//spawn thread only if we have kerb credentials
if (user.getAuthenticationMethod() == AuthenticationMethod.KERBEROS &&
!isKeytab) {
...
...
very deep nested ...
...
{code}
