Hello,

after enabling Kerberos the YARN ResourceManager failed to start. This is the content from log file:

It seems to be an issue with Zookeeper. If I execute zkCli.sh on the node where ResourceManager is installed the message "AUTH_FAILED" is displayed:

$ /usr/hdp/2.6.3.0-235/zookeeper/bin/zkCli.sh

zkCli.sh in the other nodes is working fine:

Do you have any idea about how to troubleshoot this issue?

Many thanks in advance,

Jorge.

@Jorge Florencio,

Please check the value of "yarn.resourcemanager.zk-address" in Yarn configs (Yarn -> Config -> Advanced -> Fault tolerance)

If it is set to localhost:2181 , then change it to <zk-host>:2181 and try restarting the components. Additionally perform forward and reverse DNS lookup of the hostname where RM is running.

Also, for the AUTH_FAILED in zkCli.sh is due to the zookeeper address not being passed in the command. If -server option is not passed, it assumes that zookeeper is running on local which is not the case for you. You can try running

./zkCli.sh -server <zk-host>:2181

Thanks,

Aditya

Hi Aditya,

I've checked the DNS, forward and reverse, and I've seen that "hostname -f" doesn't display fqdn. After solving this issue, all services are up and running.

Thank you!

Jorge.
