> If tokenRenewalInterval is not set, HadoopFSDelegationTokenProvider#getTokenRenewalInterval will fetch some tokens and renew them to get a interval value. These tokens did not call cancel(), resulting in a large number of existing tokens on HDFS not being cleared in a timely manner, causing additional pressure on the HDFS server.
