[jira] [Created] (HDFS-3972) Trash emptier fails in secure cluster

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.
