             Summary: Failed to restart services on PPC cluster post Ambari upgrade for IOP/HDP migration
                 Key: AMBARI-22574
                 URL: https://issues.apache.org/jira/browse/AMBARI-22574
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.6.1
            Reporter: Di Li
            Priority: Critical
             Fix For: 2.6.1


The cluster started as IOP 4.2.5 on PPC with NameNode HA enabled. I upgraded Ambari to Ambari 2.6.1 (build id 85). The NN HA setting does not matter to the issue.

After the Ambari upgrade, I can't restart services by clicking the "Restart" button on each service with that "restart needed" icon. Nor can I abort the requests.

Ambari server log contains the following error on unable to find redhat-ppc7 os type.
java.lang.RuntimeException: org.apache.ambari.server.controller.spi.SystemException: Operating System matching redhat-ppc7 could not be found

repo_version table had "redhat7" as the os type in the repository information. I worked around the issue by updating repo_version table to have redhat-ppc7 as the os type via the following SQL query: 

update repo_version set repositories='[{"OperatingSystems/ambari_managed_repositories":"true","repositories":[{"Repositories/repo_id":"IOP-4.2.5","Repositories/base_url":"http://birepo-build.svl.ibm.com/repos/IOP/RHEL7/ppc64le/4.2.5.0/20170602_1749","Repositories/repo_name":"IOP"},{"Repositories/repo_id":"IOP-UTILS-1.3","Repositories/base_url":"http://birepo-build.svl.ibm.com/repos/IOP-UTILS/RHEL7/ppc64le/1.3","Repositories/repo_name":"IOP-UTILS"}],"OperatingSystems/os_type":"redhat-ppc7"}]' where repo_version_id = 1;
