> Key: HADOOP-13590
> URL: https://issues.apache.org/jira/browse/HADOOP-13590
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 2.8.0, 2.7.3, 2.6.4
> Reporter: Xiao Chen
> Assignee: Xiao Chen
>
> 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.
