BUG-74775

The Use RedHat Satellite/Spacewalk button does not work.

To use Satellite or Spacewalk server for HDP repository management:

  • On Ambari Server, run:

    /var/lib/ambari-server/resources/scripts/configs.sh
     -u <ambari_admin_user> -p <ambari_admin_password> -port <port_ambari_is_running_on>
     set <ambari_server_host_name> <cluster_name> cluster-env repo_suse_rhel_template
     "[{{repo_id}}-DISABLED]\nname={{repo_id}}-DISABLED\n{% if mirror_list %}mirrorlist={{mirror_list}}
     {% else %}baseurl={{base_url}}{% endif %}\n\npath=/\nenabled=0\ngpgcheck=0"
  • On all the nodes managed by Ambari, run:

    sed -i 's/enabled=1/enabled=0/g' /etc/yum.repos.d/HDP*.repo

The second command disables external repositories on the nodes that have already been provisioned.

Filtering by Role on Users page in Ambari Admin Interface is slow with 1000+ users.

If you have 1000+ users from LDAP synchronized into Ambari and you attempt to filtering by Role on the Users page in Ambari Admin Interface, the results will be slow (potential 20 seconds). Reducing the number of users you have synchronized into Ambari is a way to improve this performance.

BUG-64326

If you add or remove ZooKeeper servers and you have Atlas in your cluster, you must update some Atlas properties.

If you are running Atlas in your cluster and make changes to ZooKeeper (adding or removing ZooKeeper server components), you must update the Atlas properties list below to make sure they reflect the list of ZooKeeper servers in the cluster. You can modify the following properties from Ambari Web > Services > Atlas > Configs:

atlas.audit.hbase.zookeeper.quorum
Sample: node-test0.docker.nxa.io:2181,node-test2.docker.nxa.io:2181,node-test1.docker.nxa.io:2181

atlas.graph.index.search.solr.zookeeper-url
Sample: node-test1.docker.nxa.io:2181/infra-solr,node-test0.docker.nxa.io:2181/infra-solr,node-test2.docker.nxa.io:2181/infra-solr

atlas.graph.storage.hostname
Sample: node-test0.docker.nxa.io,node-test2.docker.nxa.io,node-test1.docker.nxa.io

atlas.kafka.zookeeper.connect
Sample: node-test0.docker.nxa.io,node-test2.docker.nxa.io,node-test1.docker.nxa.io

BUG-57093

When toggling and saving the Hive service's "Enable Interactive Query" configuration, it's important to wait for the background operations associated with that change to complete before trying to toggle it once more. If you don't wait for background operations to complete and try to re-enable this feature it can cause some of the operations to fail resulting in configuration inconsistencies.

If such inconsistencies are observed then retry toggling and saving of the "Enabling Interactive Query" configuration and wait for all requests (background operations) to complete.
