FliegenKLATSCH created HDFS-16356:
-------------------------------------
Summary: JournalNode short name missmatch
Key: HDFS-16356
URL: https://issues.apache.org/jira/browse/HDFS-16356
Project: Hadoop HDFS
Issue Type: Bug
Components: journal-node
Affects Versions: 3.3.0
Reporter: FliegenKLATSCH
I see the following issue in one of 3 JournalNodes:
"Only Namenode and another JournalNode may access this servlet".
The journalnode wants to download an edit log (shortly after startup) from
another journalnode, but in the request the short username equals the (long)
principal name and thus the request gets denied.
I'll add a PR which trims the principal to the actual short name, but I am not
sure why in the first place the request token contains the full principal name
and what the desired name actually is. Maybe I have a misconfiguration on my
end?
