Occasionally No Views listed in AMBARI

New Contributor

Occasionally No views listed in AMBARI after some attempts (logout/login) it's automatically started working fine without changed anything. I have verified the log (ambari-server.log). I don't see any issues except below.

I'm getting below error "No Such User" when ever I'm facing that "No Views" screen. I'm not getting the same when all the views displayed successfully.

Will continue connection to Zookeeper server without SASL authentication, if Zookeeper server allows it.

Could you please some one help me to address this issue?

thanks in advance.

ShellBasedUnixGroupsMapping:87- got exception trying to get groups for user x: id: x:No such user shells out with the bash -c groups command to resolve a list of groups for a user. It may be that there are simply occasional user-to-group lookup issues on the server itself. If you log into this host as said user and run 'bash -c groups', is it consistently successful in resolving the groups or are there occasional lookup errors?
