Szilard Nemeth commented on HADOOP-15717: ----------------------------------------- Hi [~gabor.bota]! The reason for logging the exception is that it helps troubleshooting what caused the {{IOException}}, 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 see that you 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. Hope this is clear. > TGT renewal thread does not log IOException > ------------------------------------------- > > Key: HADOOP-15717 > URL: https://issues.apache.org/jira/browse/HADOOP-15717 > Project: Hadoop Common > Issue Type: Improvement > Reporter: Szilard Nemeth > Assignee: Szilard Nemeth > Priority: Major > Attachments: HADOOP-15717.001.patch > > > See here: > https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/UserGroupInformation.java#L918 -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
