Hi, I'm CLEO! Something exciting is coming to the Community. Stay Tuned!
SYMPTOM: During processes like adding a service, or upgrading, Ambari UI complains package not found for installation. From the log we can see that Ambari is searching for a repo higher version than cluster's current HDP version
For example: -- Current version : Ambari Version 1.7.0 and HDP 2.2.0 -- But Ambari is searching in repo version for 2.2.8
ROOT CAUSE: It seems that /var/lib/ambari-server/resources/stacks/HDP/<VERSION>/repos/repoinfo.xml file has been updated with wrong latest version info.
RESOLUTION:
1. comment out the below line in file /var/lib/ambari-server/resources/stacks/HDP/<VERSION>/repos/repoinfo.xml
'<latest>http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json</latest>'
2. Open Ambari database, and check content of table metainfo . For example :
In case the metainfo_key "repo:/HDP/2.2/redhat6/HDP-<VERSION>:baseurl" is missing, use following command to add content to table : ' INSERT INTO metainfo VALUES ('repo:/HDP/2.2/redhat6/HDP-<VERSION>:baseurl', 'http://public-repo-1.hortonworks.com/HDP/centos6/2.x/GA/2.2.0.0'); '
3. restart ambari server and agents
4. yum clean all command on service master hosts
5. re-install or re-run upgrade
