Haohui Mai created HADOOP-10015: ----------------------------------- Summary: UserGroupInformation prints out excessive ERROR warnings Key: HADOOP-10015 URL: https://issues.apache.org/jira/browse/HADOOP-10015 Project: Hadoop Common Issue Type: Bug Reporter: Haohui Mai Assignee: Haohui Mai
In UserGroupInformation::doAs(), it prints out a log at ERROR level whenever it catches an exception. However, in some cases IOExceptions are expected -- For example, the upp (e.g., calling exists() in filesystem). As a result, these error logs are benign but they are printed at the ERROR level, which confuses the operators. -- This message was sent by Atlassian JIRA (v6.1#6144)
