"Failed to login" error with Yarn App Timeline Server

kabalax — Mon, 29 Aug 2016 15:25:27 GMT

Hi,

I'm having problems starting Yarn App Timeline Server (HDP-2.4.0.0-169 kerberized cluster with Ambari 2.2.2.0).

Everything was working fine for several months until we had to reallocate servers to a different data center therefore the cluster had to be shut down. I'm able to start Active and Standby ResourceManagers (along with all NodeManagers), but App Timeline Server fails with the following in the logs:

yarn.service.keytab is present on hdp-nn01.local.net, and krb5.conf seem to be the intact.

Any assistance would be greatly appreciated.

Thanks.

@Teddy Brewski

Can you please try kinit with the yarn.service.keytab and see whether it is successful. You will be able to get the yarn service principal using below command

klist -kt /etc/security/keytabs/yarn.service.keytab

Take the principal name from the previous command and run

kinit -kt /etc/security/keytabs/yarn.service.keytab  ${yarn-service-principal-name}

Thank you Santhosh. It seems that it expired?

$ klist -kt /etc/security/keytabs/yarn.service.keytab

Executing kinit -kt /etc/security/keytabs/yarn.service.keytab yarn/hdp-nn01.local.net@HADOOP.LOCAL gives me

kinit: Password incorrect while getting initial credentials

but I can't recall setting up the password.

Thanks.

@Teddy Brewski

Looks like something is wrong with principal yarn/hdp-nn01.local.net@HADOOP.LOCAL. Can you please check whether the account exists in KDC or is it probably blocked ?. Run below command on the machine where your kdc server is running.

kadmin.local -q "get_principal yarn/hdp-nn01.local.net@HADOOP.LOCAL"

@Teddy Brewski

Can you please re-import the keytab file and try kinit on the new keytab ? Below is the command to fetch the keytab.

kadmin.local -q "xst -k  ~/yarn.service.keytab yarn/hdp-nn01.local.net@HADOOP.LOCAL"
