[jira] [Created] (HADOOP-13590) Retry until TGT expires even if the
UGI renewal thread encountered exception
Xiao Chen created HADOOP-13590:
----------------------------------
Summary: Retry until TGT expires even if the UGI renewal thread encountered exception
Key: HADOOP-13590
URL: https://issues.apache.org/jira/browse/HADOOP-13590
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 0.22.0
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.
