Make sure your SecondaryNamenode, or standby Namenode is running it will keep checkpointing and removing old edit logs.

That worked, thanks! Now I can see the option on the ambari UI.

Is there a workaround for this problem, which doesn't involve upgrade/downgrade?

I think its not able to get to the Active Directory. I would suggest setting default realm if it is not set by 'ksetup /setrealm REALM.COM ' assuming you already did 'ksetup /addkdc REALM.COM adhostname.com'

klist -kt /etc/security/keytabs/hive.service.keytab to find out exact principal name you need to kinit with.

A very good page to refer is this one https://community.hortonworks.com/articles/2473/rolling-upgrade-express-upgrade-in-ambari.html. I was facing other problem and this page helped me. HTH.

When I start a namenode using CM web UI it starts /usr/lib64/cmf/service/hdfs/hdfs.sh, but when I run the same script from console it is not able to find various env variables. Can you please help me out with this? There is not documentation regarding this, one doc I found was starting namenode when CDH is installed standalone. Thanks! edit#1 I guess I would be able to use cm api but I would rather just run the script that cm manager runs under the hood 😉
