This has me a little confused as well. There are three counters for this: - (1) Ambari Dashboard has "CPU Usage" which always seems to look low. (makes sense for our env) - (2) YARN has "CPU Utilization" for "% of total cores assigned to containers" which never goes under 40% (makes sense for our env) - (3) YARN has "Cluster CPU" for "% of CPU utilization across node manager hosts" which is always between 50%-95% (This makes no sense in our env) So, when our jobs run, 1 doesn't climb much, 2 doesn't move much, 3 quickly hits 95%. We want to run our jobs faster but between 1 & 3 I can't tell if we are high utilization of CPU or not. Host page CPU seems to trend with 1 (quiet) But am I hitting a ceiling? 3 can't go any higher

The issue got resolved. I had to take out the line "securityManager.realms = $activeDirectoryRealm" from my config and that resolved the issue. I dont see anything wrong in the line I took out. However, I believe this is an optional config.

@Ekantheshwara Basappa You probably found your way past this by now. 🙂 I ran into this problem today and the issue ended up being the "Group name attribute" was not set correctly. I was able to solve it by using ldapsearch to query for a group from the Active Directory server and then read how it listed its values. For example, this search will return all groups that exist within the example.com AD: ldapsearch -o ldif-wrap=no -LLL -D any_user@example.com -W -h <ldap_ip_address> -p 389 '(objectClass=group)' -b "DC=example,DC=com" Here is what a single response from the above search looks like (minus the unnecessary bits): dn: CN=my_group,OU=Groups,DC=example,DC=com
objectClass: top
objectClass: group
cn: my_group
member: CN=user3,OU=Users,DC=example,DC=com
member: CN=user2,OU=Users,DC=example,DC=com
member: CN=user1,OU=Users,DC=example,DC=com
distinguishedName: CN=my_group,OU=Groups,DC=example,DC=com
name: my_group
objectCategory: CN=Group,CN=Schema,CN=Configuration,DC=example,DC=com
Reviewing this ldapsearch response, you can figure out what your entries should be for ldap-sync in Ambari Notice the group's name attribute is "cn" and that group member attribute is "member". This is what solved it for me anyway...
