> In a secure HA 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.
