One important point: If the version of the software in use is 6.2, please let me know as I'll have additional license-related information to provide.   Thank you kindly.   Best, Alex ... View more

Thank you for reaching out to Cloudera Support via our Community. My name is Alex and I'm a member of the Customer Advocacy team.   I can confirm the following 2 very important points:   In accordance with our general policies and procedures, new enterprise license keys are provided to customers on the start date of the renewal/contract in question. Because of this, the expiration of an enterprise license key causes no product impact aside from a banner message in Cloudera Manager. You can be assured that a Cloudera Enterprise cluster will exhibit absolutely no adverse effects due to key expiration.   If you would like to provide me specifics of the customer/partner contract in question, I'll be happy to deliver additional details regarding when the key will be delivered and to whom it will be sent. Please provide me a contact email address and I will respond directly.   Thank you kindly.   Best, Alex ... View more

Once the Enterprise License Key is removed, all of the enterprise functionality that is enabled by the Key is no longer going to be available. The functionality is documented here.   For example, the Enterprise version of the software enables the following (as well as other very important services such as Encryption and Key Management) =>   ========== Advanced Features: Operational Reporting; Multi-Tenant Quota Management; Configuration History & Rollbacks; Rolling Updates & Service Restarts; SNMP Support; Support Integration (including scheduled diagnostics & proactive maintenance); Fine-Grained User Roles; & Automated Backup & Disaster Recovery ==========   In terms of preparing your cluster for the removal of the Enterprise License Key, it's going to depend on what/which advanced features, or, other functionality you're using that is only available by virtue of using the Key.   Without knowing the specifics of how the cluster is configured or running, it's not possible to confirm the steps that should be performed in order to ensure you won't have an impact once the Key is removed.   If your cluster is dependent on any of the advanced features or other Enterprise functionality noted in the sheet I linked above, I would recommend proceeding with extreme caution before removing the License Key. If that is the case, I would recommend speaking to your Sales Representative at Cloudera to discuss options for being able to continue using the Enterprise version of the software.   Hope this helps.   Best, Alex ...

This question has also been addressed here, just FYY Tina:   http://community.cloudera.com/t5/Cloudera-Manager-Installation/From-Cloudera-Manager-trial-to-Cloudera-Manager-Express/m-p/55005#M1385?eid=1&aid=1 ... View more

Here's a page that describes the differences between the "Cloudera Enterprise" and "Cloudera Express" versions:   https://www.cloudera.com/documentation/enterprise/latest/topics/cm_ig_feature_differences.html#cmfeig_topic_5_1   To specifically answer your question, the expiration of a trial license key will indeed remove features such as LDAP authentication to Cloudera Manager, as noted in the table on the above-referenced document. So, if your CM had been set up and configured to authenticate against an LDAP store it's possible that, yes, this will no longer be working correctly.   But, generally speaking, the expiration of a trial license key will not render a cluster un-usable, it's just simply that the enterprise functionality is no longer going to be available.   Best, Alex ...

Thank you for looping me in, @cjervis.   I can confirm that if a trial license key has expired, there's 2 possible paths forward.   If by "trial" you're speaking of a formal enterprise support trial issued by Cloudera, the key does indeed need to be removed as noted earlier in this the thread linked by Cy.   If by "trial" you're referring to the 60-day key that is capable of being downloaded directly from cloudera.com, there is no action needed. Upon the 60 days expiring, the cluster will revert back to express.   If I can be of any further assistance please let me know. Thank you kindly.   Best, Alex ... View more

https://www.cloudera.com/documentation/enterprise/5-6-x/topics/cm_ig_feature_differences.html Here's a nice side-by-side showing the functionality that's enabled by using the enterprise license key. In summary, those items will no longer be available. Does it mean the cluster will be inoperable? Definitely not. But, any functionality tied to the specific items in the document will be impacted. Hope this helps. Any further questions please let us know. ... View more

Removal of the enterprise license key will revert the cluster back to express. The documentation details the enterprise functionality that is enabled with the key in use. That functionality would no longer be available once the key isn't in place. ... View more

As per the contractual enterprise license agreement's language, the enterprise license key must be removed as per the instructions here if there's no further enterprise contract in place:   https://cloudera-portal.force.com/articles/KB_Article/Removing-Cloudera-Manager-Enterprise-License   Hope this helps. ...
