If the 'renew until' date is the same as the 'valid starting' date, the ticket cannot be renewed. Please check your KDC configuration, and the ticket renewal policy (maxrenewlife) for the 'hue-ub22-32332@ADSRE.COM' and `krbtgt' principals.

For CentOS/RHEL:

1. On the KDC host, add the max_renewable_life and max_life properties in the configuration file.

[root@ce7-f1-node01 ~]# cat /var/kerberos/krb5kdc/kdc.conf

[realms]

    ADSRE.COM = {

        database_name = /var/kerberos/krb5kdc/principal

        acl_file = /var/kerberos/krb5kdc/kadm5.acl

        supported_enctypes = aes256-cts-hmac-sha1-96:normal aes128-cts-hmac-sha1-96:normal des3-cbc-sha1:normal des-cbc-md5:normal arcfour-hmac-md5:normal

        max_renewable_life = 7d 0h 0m 0s           ## add    

        max_life = 12h 0m 0s                       ## add

    }

2. Once added and saved, restart KDC and KAdmin (use the following commands) and regenerate keytabs followed by restarting the Hue service from the Ambari UI.

sudo systemctl restart krb5kdc

sudo systemctl restart kadmin

For Ubuntu:

1. On the KDC host, add the max_renewable_life and max_life properties in the configuration file.

root@ub22-f1-node01:~# cat /etc/krb5kdc/kdc.conf

[realms]

    ADSRE.COM = {

        database_name = /var/lib/krb5kdc/principal

        acl_file = /etc/krb5kdc/kadm5.acl

        max_renewable_life = 7d 0h 0m 0s        ## add

        max_life = 12h 0m 0s                    ## add

    }

2. Once added and saved, restart KDC and KAdmin (use the following commands) and regenerate keytabs followed by restarting the Hue service from the Ambari UI.

sudo systemctl restart krb5-kdc

sudo systemctl restart krb5-admin-server

In addition to the KDC configuration changes, make sure to run these commands on the Kerberos Key Distribution Center (KDC) using the kadmin.local or kadmincommand-line interface:

# Allow renewable tickets for hue principal

modprinc -maxrenewlife "90 days" +allow_renewable <principal-name>@<REALM>

​

# Set renewal policy for the realm's Ticket Granting Ticket (TGT)

modprinc -maxrenewlife "90 days" krbtgt/<REALM>

​

eg

modprinc -maxrenewlife "90 days" +allow_renewable hue@ADSRE.COM

modprinc -maxrenewlife "90 days" krbtgt/ADSRE.COM

Isilon OneFS

README for Isilon Ambari Management Pack 1.0.3.0 for OneFS

The Isilon Ambari Management Pack for OneFS is a software component that integrates OneFS as a service into a Hadoop cluster via Ambari. This management pack allows an Ambari administrator to manage OneFS as a HDFS storage service, providing native namenode and datanode capabilities similar to traditional HDFS. The management pack is OneFS release-independent and can be updated between releases if necessary.

Prerequisites

This management pack is compatible with the following OneFS versions:

• OneFS 8.1.2
• OneFS 8.2.0
• OneFS 8.2.1
• OneFS 8.2.2
• OneFS 9.0.0

Install OneFS Mpack

To install the Isilon management pack, perform the following steps:

1. Run the installation command:

ambari-server install-mpack --mpack=ambari-mpacks-isilon-onefs-1.0.3.0.tar.gz --verbose

2. Update the symbolic links for the OneFS service:

cd /var/lib/ambari-server/resources/stacks/ODP/3.0/services/

rm -f ONEFS

ln -s /var/lib/ambari-server/resources/mpacks/onefs-ambari-mpack-1.0.3.0/common-services/ONEFS/1.0.0/ ONEFS

​

cd ../../3.1/services/

rm -f ONEFS

ln -s /var/lib/ambari-server/resources/mpacks/onefs-ambari-mpack-1.0.3.0/common-services/ONEFS/1.0.0/ ONEFS

​

cd ../../3.2/services/

rm -f ONEFS

ln -s /var/lib/ambari-server/resources/mpacks/onefs-ambari-mpack-1.0.3.0/common-services/ONEFS/1.0.0/ ONEFS

3. Restart the Ambari Server:

ambari-server restart

After running the above commands, you will see the following message:

INFO: Management pack onefs-ambari-mpack successfully installed! Please restart ambari-server.

INFO: Loading properties from /etc/ambari-server/conf/ambari.properties

Ambari Server 'install-mpack' completed successfully.

To uninstall the management pack, run the following command:

ambari-server uninstall-mpack --mpack-name=onefs-ambari-mpack

Then, remove the following directories:

rm -rf /var/lib/ambari-server/data/tmp/isilon-onefs-mpack*/ /var/lib/ambari-server/resources/stacks/ODP/3.0/services/ONEFS /var/lib/ambari-server/resources/stacks/ODP/3.1/services/ONEFS /var/lib/ambari-server/resources/common-services/ONEFS /var/lib/ambari-agent/cache/stacks/ODP/3.0/services/ONEFS /var/lib/ambari-agent/cache/stacks/ODP/3.1/services/ONEFS /var/lib/ambari-agent/cache/common-services/ONEFS /var/lib/ambari-agent/cache/stacks/ODP/3.2/services/ONEFS

Important Notes

• A performance issue with OneFS and Ambari has been identified when Apache HBase is configured. Setting the hbase.wal.provider value to filesystem resolves this issue.
• When installing the 1.0.3.0 Ambari Management Pack on a Hadoop cluster with a new deployment of ODP, the hbase.wal.provider value will be automatically set to filesystem.
• If the Hadoop cluster already has Ambari and HBase configured, the hbase.wal.provider value must be manually configured in the Ambari UI. Follow these steps to configure it:
  1. Log in to the Ambari UI.
  2. Click the 'HBase' service in the left panel, then click the Configs tab, and finally click the Advanced tab.
  3. In the Custom hbase-site section, look for the hbase.wal.provider key. If it does not exist, add it by clicking Add Property.
  4. Enter the following in the Properties field: hbase.wal.provider=filesystem
  5. Click ADD and then Save to save the configuration. Restart Ambari if prompted to apply the setting.

Resolved Issues

• Setting the hbase.wal.provider value to filesystem in the Ambari UI resolves the performance issue.
• The OneFS Release Notes can be found on the customer support site: Support for PowerScale OneFS | Overview | Dell US
• The following documents, available on the customer support site, provide instructions for downloading and installing the Ambari Management Pack for Isilon OneFS:
  • PowerScale OneFS With Hadoop and Installation Guide
  • PowerScale OneFS With Hadoop and Hadoop for Kerberos Installation Guide

Upgrade Isilon Mpack
