------------------------------------
Summary: When using SPNEGO, NN should not try to log in using KSSL
principal
Key: HDFS-3727
URL: https://issues.apache.org/jira/browse/HDFS-3727
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 1.2.0
Reporter: Aaron T. Myers
Assignee: Aaron T. Myers
When performing a checkpoint with security enabled, the NN will attempt to
relogin from its keytab before making an HTTP request back to the 2NN to fetch
the newly-merged image. However, it always attempts to log in using the KSSL
principal, even if SPNEGO is configured to be used.
