--------------------------------------------
Summary: Express Upgrade: didn't finalize HDFS, improve robustness
for HA
Key: AMBARI-13913
URL: https://issues.apache.org/jira/browse/AMBARI-13913
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.0, 2.1.3
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 2.2.0, 2.1.3
For ExpressUpgrade,
1. We started the NameNodes with "-rollingUpgrade started" but were calling the
wrong finalize command, "-finalizeUpgrade" instead of "-rollingUpgrade
finalize".
2. In HA, if safemode was already on, then the prepare step would fail since
the grep command reported an error.
3. In HA, we now check both NameNodes to come out of safemode. Before, this
would only run on the active one.
