Todd Lipcon created HDFS-3972: --------------------------------- Summary: Trash emptier fails in secure cluster Key: HDFS-3972 URL: https://issues.apache.org/jira/browse/HDFS-3972 Project: Hadoop HDFS Issue Type: Bug Components: name-node Affects Versions: 2.0.1-alpha, 3.0.0 Reporter: Todd Lipcon Assignee: Todd Lipcon Priority: Critical
In a secure cluster, we're seeing the following issue on the NN when the trash emptier tries to run: WARN org.apache.hadoop.fs.TrashPolicyDefault: Trash can't list homes: java.io.IOException: Failed on local exception: java.io.IOException: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]; Host Details : local host \ is: "xxxxx"; destination host is: "xxxx":8020; Sleeping. The issue seems to be that the trash emptier thread sends RPCs back to itself, but isn't wrapped in a doAs. Credit goes to Stephen Chu for discovering this. -- This message is automatically generated by JIRA.
