> The UGI has a background thread to renew the tgt. On exception, it 
> [terminates 
> itself|https://github.com/apache/hadoop/blob/bee9f57f5ca9f037ade932c6fd01b0dad47a1296/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/UserGroupInformation.java#L1013-L1014]
> If something temporarily goes wrong that results in an IOE, even if it 
> recovered no renewal will be done and client will eventually fail to 
> authenticate. We should retry with our best effort, until tgt expires, in the 
> hope that the error recovers before that.
