Starting services takes a long time.

michael3 — Fri, 16 Sep 2022 11:32:18 GMT

I recently installed HDP 2.6 after uninstalling HDP 2.5.

Starting and restarting services takes a long time now. Is this expected behavior?

The issue may be related to this warning:

@Michael Londeen

Are you using ActiveDirectory or LDAP in your setup?

Can you please try setting the "ignore_groupsusers_create" parameter value to "true" and then ry restarting the services again?

Example:

# /var/lib/ambari-server/resources/scripts/configs.sh set  <AMBARI_FQDN> <CLUSTER_NAME> cluster-env  "ignore_groupsusers_create"  "true"

It will made it skip users and groups creating part. Basically enabling this flag, user have to create users/groups on his own, So Ambari will not attempt to create the hadoop group for you and expected the group exists.

Neither AD or LDAP. Local users/groups only.

Is there a way to do this on a per-server basis?

I have some edge nodes where restarting services doesn't seem to work and I get this error....
