Hello Community

Ambari is not able to start namenode: in fact, it's not able to execute commande 'ambari-sudo.sh su hdfs -l -s /bin/bash -c ...'. When I try to execute the whole command manually, I'm asked to enter password. Folowing is the stderr.out

has anyone an idea about what cound be the reason?

Thank you

I found the cause of the problem. it's configuration matter.

in fact namenode was installed on master01 but following parameter was set with worker02 (on which no namenode) :

dfs.namenode.http-address: worker02.cl02.sr.private:50070 instead of master01.cl02.sr.private:50070

the configuration was altered because the cluster was taken to HA configuration then taken back to non HA. then one of the namenodes was deleted (the one on worker02) without paying attention that the remaining configuration was pointing to worker02.

hope I'm clear 🙂

@mohamed sabri marnaoui

Are you running the Ambari agent as a non-root user? If so, make sure that your sudoers file is correct per this documentation:

http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.2/bk_Security_Guide/content/_sudoer_configurat...
