Subject [jira] [Updated] (HADOOP-15717) TGT renewal thread does not log IOException
Date Tue, 04 Sep 2018 14:59:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15717?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Szilard Nemeth updated HADOOP-15717:
------------------------------------
    Description: 
The reason for logging the IOexception is that it helps troubleshooting what caused the exception,
as it can come from two different calls from the try-catch.
I came across a case where tgt.getEndTime() was returned null and it resulted in an NPE.
I can see that [~gabor.bota] handled this with HADOOP-15593, but apart from logging the fact
that the ticket's {{endDate}} was null, we have not logged the exception at all.

The code should be updated here: https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/UserGroupInformation.java#L918
