Hello @ashokaakula As per [1], the Master Password isn't recoverable in the event of the same being lost. As such, We shall request your Team to engage Cloudera Support, if your Team have lost the same without further delay.

Hello @pacman Thanks for using Cloudera Community. HBase handles such scenario by Read Merge. A Read "Merges" Key Values from the Block Cache, MemStore, and HFiles in the following steps: First, the Scanner looks for the Row Cells in theBlock Cache (Read Cache). Next, the Scanner looks in the MemStore (Write Cache). If the Scanner does not find all of the Row Cells in the MemStore and Block Cache, then Hfiles are referred. Hope the above answers your query. If Yes, Kindly mark the Post as Resolved. Regards, Smarak

Hello @quangbilly79 Thanks for using Cloudera Community. The Link [1] applies to CDE Service, which is available on Private Cloud & Public Cloud. In CDP Public Cloud, Your Team need to connect to the CDP Management Console & access the CDE Service as documented in [1]. In CDP Private Cloud, You need to install Data Service [2] to access CDE Service, upon which your Team can Schedule Job. The Cloudera Manager of CDP Private Cloud is used to install Data Service [2] & CDE is available after successful installation on Data Service. Without Data Service, Oozie can be used by your Team as shared above by Steven. Kindly review & let us know if you have any queries. Regards, Smarak [1] Scheduling jobs in Cloudera Data Engineering [2] CDP Private Cloud Data Services: Documentation | CDP Private Cloud (cloudera.com)

Hello @GregDol Thanks for using Cloudera Community. This is an Old Post, yet I am sharing a review for other Community Users, in case they encounter the concerned issue. Reviewing the Post indicates the Issue is likely caused by missing "rt.jar" in the JDK used by the Solr Service. In other words, the concerned Class "java.time.zone.ZoneRulesProvider" is present in "/usr/java/jdk1.8.0_232-cloudera/jre/lib/rt.jar" for CDP Cluster (Path & Version may be different for Customer). The concerned JDK is used by the various Services running including Solr. In your scenario, the concerned Class appears to be missing. Assuming your team wish to confirm whether a JAR consists of the Class, you may use Command [ /usr/java/jdk1.8.0_232-cloudera/bin/jar -tvf /usr/java/jdk1.8.0_232-cloudera/jre/lib/rt.jar] to list the Classes, which should include "java.time.zone.ZoneRulesProvider" as well. If your Team is using any different JDK, Review the same & ensure the "rt.jar" is present for Class "java.time.zone.ZoneRulesProvider" to be loaded successfully. Regards, Smarak

Hello @sekhar1 Thanks for using Cloudera Community. Generally such Exception are received if Traffic from your Machine isn't allowed to or from the Security Group linked with the VPC wherein the CML Workspace instances are deployed. Check if the Kubernetes Pods associated with the CML Workspace Kubernetes Cluster are Up/Running. If Yes, Such Exception should be reviewed from a Network Standpoint only. You may reach out to your Customer's AWS/Platform Team to review the Traffic between your Machine & the VPC within which the CML Workspace is deployed. Regards, Smarak

Hello @Nghia Thanks for using Cloudera Community. Based on the Post, the CDE Airflow UI isn't working for you. Few things we can request you to review further on the Post: Whether other UIs like Job Page is opening for you. Ensure you have performed [1] i.e. the "After You Finish" Section, which is required for each CDE Virtual Cluster. Ensure the UI are reviewed in Incognito Mode to rule out any Caching concerns. Ensure the Pods running in the "dex-app-jsx4msml" are running correctly. If all above Checks are done yet the Issue persists, We would suggest engaging Support as any further troubleshooting would require sharing the Logs over the Public Community forum, which may have Customer's details. We shall mark the Post as Resolved now. If you have any concerns, Feel free to Update the Post likewise. Regards, Smarak [1] https://docs.cloudera.com/data-engineering/1.3.4/manage-clusters/topics/cde-private-cloud-create-cluster.html

Hello @QiDam As stated by JD above, the CDE Service relies on Ozone Service on Base Cluster. If Ozone Service wasn't in Healthy State, the CDE Service enabling would fail with similar tracing as shared by you. We would recommend the following checks: Ensure Ozone Service is Up & Running on Base Cluster. Create a new Environment & check CDE Service enabling on the new Environment. If the above CDE Service enabling on new Environment is Successful, Reattempt the CDE Service enabling on the existing Environment. If the above Suggestion doesn't help, We would suggest engaging Support as any further troubleshooting would require sharing the Logs over the Public Community forum, which may have Customer's details. We shall mark the Post as Resolved now. If you have any concerns, Feel free to Update the Post likewise. Regards, Smarak

Hello @sfdragonstorm & @pacman In the Region Name "img,0006943d-20150504220458043384375D00000002-00093,1527295748538.7b45a9f6f5584fc50b3152d41a5323a2.", the Table Name is "img", StartKey is "0006943d-20150504220458043384375D00000002-00093", Timestamp is "1527295748538" & "7b45a9f6f5584fc50b3152d41a5323a2" is the Region ID. Under HBase Data Directory, each Table Directory would have Region-Level Directories as identified by Region ID ("7b45a9f6f5584fc50b3152d41a5323a2" in Example). The Region ID is an MD5 encoded string for the Region Name & generated by HBase itself. Refer [1], if your Team wish to review the same.
