> Key: AMBARI-12205
> URL: https://issues.apache.org/jira/browse/AMBARI-12205
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Reporter: Alejandro Fernandez
> Assignee: Alejandro Fernandez
> Priority: Critical
> Fix For: 2.1.0

> Fix 3 issues related to Rolling Upgrades.
> 1. RU orchestration first upgrades the standby NameNode, then the active.
> However, HDFS utils.py only kills ZKFC on the active NameNode; instead, this
> should be on both active and standby.
> 2. When Ambari installs the packages of an HDP repo before RU, if the host
> only has AMS, then "hdp-select versions" will not report any values.
> Technically, this is ok for this host, so Ambari should ignore this. However,
> if the host does not report any delta of versions and was not able to read a
> version from /var/lib/ambari-agent/data/repo_version_history.json and does
> contain the stack's root folder (e.g., /usr/hdp), then it should result in an
> error.
> 3. In RU, the flume stop command issues a kill, but does not supply a signal,
> such as -15
