HDP upgrade 2.6.2 to 3.1 , Finalize Upgrade Pre-Check failed

Expert Contributor

Hi,

during upgrading from HDP 2.6.2 to HDP 3.1, we faced some issues "starting 2 data nodes was giving OOM exception, so we had to increase the java heap size manually and start them manually as well" that required manual steps , now we are at "Finalize Upgrade Pre-Check", and everything looks fine in the cluster, so we need to bypass this step in the upgrade, as its giving us error below

Upgrade did not succeed on 2 hosts
Your options:
Pause Upgrade, delete the unhealthy hosts and return to the Upgrade Wizard to Proceed.
Perform a Downgrade, which will revert all hosts to the previous stack version.


thanks

Hi @Tarek Abouzeid,


Not sure if you where able to bypass this issue ,

But I have few troubleshooting checks that might help


Check 1 : we should navigate to problamatic two nodes and see if the hdp-select command lists the version 3.1 or not.


Check 2 : navigate to ambari-database , inspect the table :


select * from host_version order by host_id;
select host_id,host_name from hosts;


and you will know two of your culprit hosts will be in OUT_OF_SYNC state .

make it current based on the repo_version_id and restart ambari.


Hope this helps
