[jira] [Updated] (AMBARI-12949) Downgrade fails with err: 500
status code received on POST method for API:
/api/vi/clusters/mycluster/upgrades
[ https://issues.apache.org/jira/browse/AMBARI-12949?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Di Li updated AMBARI-12949:
---------------------------
Description:
I have a 4 node HDP 2.2 cluster where I created a configuration group to apply customized oozie_heap_size to the Oozie server and one of the Oozie client. I was able to rolling upgrade the cluster to HDP 2.3, but when I clicked Downgrade button on the Finalize step. The Ambari UI immediately threw error message "500 status code received on POST method for API: /api/vi/clusters/mycluster/upgrades"
Checking the Ambari server log, it reported a nullpointer error when trying to load the designed configurations
Aug 30, 2015 11:01:07 PM com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException
SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container
java.lang.NullPointerException
at org.apache.ambari.server.state.host.HostImpl.getDesiredHostConfigs(HostImpl.java:1349)
Digging around in the database, I saw that the oozie-env (where I had a configuration group) had no version_tag set with "selected" as 1.
Manually setting the version1 row to have selected = 1, restart server and then I was able to run downgrade. However, the downgrade failed to mark itself as finished, and my Ambari WEB UI remained in this "Downgrade:Aborted" state and I can't restart components anymore (as in most of the UI features are disabled as the UI still thinks it's in the middle of an downgrade).
ambari=> select * from clusterconfigmapping where type_name = 'oozie-env';
cluster_id | type_name | version_tag | create_timestamp | selected | user_name
