Review request for Ambari, Alejandro Fernandez, Nate Cole, and Robert Levas.
Bugs: AMBARI-15482
https://issues.apache.org/jira/browse/AMBARI-15482
Repository: ambari
Description
-------
During an upgrade, the HDFS NameNode(s) are restarted with the
{{-rollingUpgrade}} flag. However, it's possible to get to the end of an
upgrade and decide to "Finalize Later".
This allows the cluster to run in the upgraded state before committing to the
upgrade. Full cluster control is returned via the Ambari web client.
Administrators can then decide to restart a NameNode. Upon restarting the
NameNode, it will produce an error that it was not started with the
{{rollingUpgrade}} flag.
It seems that as long as an upgrade has not been finalized, the NameNode(s)
must be started with the {{rollingUpgrade}} to allow them to function properly.
STR:
- Perform a rolling upgrade from HDP 2.2 to 2.3 (or 2.3 to 2.4); as long as
there is a major version change.
- Before finalization, say "Finalize Later". All services should be up and
green.
- Now restart a NameNode
