---------------------------------
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.
