upgradeHelper question

I’m trying to upgrade from the HDP 2.1 to HDP 2.2 stack. Somewhere, I must have made a mistake
because some configurations seem to be wrong (for instance, the wrong class name for the timeline server,
and when I try to start region servers they complain that JAVA_HOME is undefined and they cannot find the JDK).

I tried rerunning the upgradeHelper.py update-configs command a second time, but 
it fails with lots of verification errors. Can this script only be run once? How do I
determine if my configurations are the correct ones?

Thanks.

Brian

Yes, I used the JSON catalog file and followed the procedure in the docs.
These problems have all been resolved. The primary fix seems to have
been doing a ‘yum clean’ on all of the cluster nodes. The cluster
upgrade is complete with all services green and no alerts.

Hi Brian,

Did you use the UpgradeCatalog_2.1_to_2.2.json file?

python upgradeHelper.py --hostname $HOSTNAME --user $USERNAME --password
$PASSWORD --clustername $CLUSTERNAME --fromStack=2.1 --toStack=2.2.x
--upgradeCatalog=UpgradeCatalog_2.1_to_2.2.x.json update-configs


As described in
http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.2.0/bk_upgrading_hdp_ma
nually/content/ch_upgrade_2_1.html

http://docs.hortonworks.com/HDPDocuments/Ambari-2.0.1.0/bk_upgrading_Ambari
/content/_upgrading_the_hdp_stack_from_21_to_22.html


Do you have a backup of the Ambari DB?

Thanks,
Alejandro
