[jira] [Updated] (AMBARI-12205) RU - Misc issues: ZKFC not upgraded
on Standby NN; Flume kill needs signal; Package Installation fails when
host has no Stack components
[ https://issues.apache.org/jira/browse/AMBARI-12205?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alejandro Fernandez updated AMBARI-12205:
-----------------------------------------
Description:
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
