Jonathan Hurley updated AMBARI-19617: ------------------------------------- Attachment: AMBARI-19617.patch > Restarting Some Components During a Suspended Upgrade Fails Due To Missing > Upgrade Parameters > --------------------------------------------------------------------------------------------- > > Key: AMBARI-19617 > URL: https://issues.apache.org/jira/browse/AMBARI-19617 > Project: Ambari > Issue Type: Bug > Components: ambari-server > Affects Versions: 2.5.0 > Reporter: Jonathan Hurley > Assignee: Jonathan Hurley > Priority: Critical > Fix For: 2.5.0 > > Attachments: AMBARI-19617.patch > > > While attempting to restart a component that has complicated upgrade logic, > the upgrade parameters are not sent to the agents. This can cause some > components to fails during a suspended upgrade restart. > Example: > - Begin express upgrade from {{2.3.6.0-3796}} to {{2.5.3.0-37}} > - {{HIVE_METASTORE}} couldn't start b/c of a missing Kerberos property: > {code} > resource_management.core.exceptions.Fail: Configuration parameter > 'hive.server2.authentication.kerberos.principal' was not found in > configurations dictionary! > {code} > - Chose to {{Ignore and Proceed}} which means that none of the Metastore SQL > files ran. > - Paused the upgrade (presumably at Finalize) and try to start Metastore. It > fails to start because the new HDP 2.5 bits are using a non-upgraded > database. That causes the {{-info}} option to fail and makes Ambari think it > needs to run {{-initSchema}}. > RCA: Metastore failed to start during upgrade and the admin chose to skip it. > This caused schema upgrade logic not to run. Ambari can examine the > {{upgrade_suspended}} property to determine if we need to run upgrade > commands while restarting Metastore during an upgrade. > However, it might be more prudent to simply send along the suspended upgrade > properties so that any actions which might need to happen (such as invoking > an upgrade script during the restart) can happen when the upgrade is > suspended. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
