您好，请看一看下面的解决办法[1]： "12. Error If npm is executed under the root account, it will change the uid to the current account, or the value of the uid is obtained from the user configuration file, and the default value of uid is nobody. So when you run npm install under the root account, you need to change unsafe-perm Option plus. Solve (and then re-edit): # find ~/.m2/repository/ -name "*.lastUpdated" -exec rm -rf {} \; # mvn -B clean install rpm:rpm -DnewVersion=2.7.3.0.0 -DskipTests -Dpython.ver="python >= 2.6" -Drat.skip=true -X -rf :ambari-admin"   [1] https://www.programmersought.com/article/72684156755/ ...

Hello @VadymDemchuk ,   thank you for the deep-analysis. If I understand correctly, the process fails at the hostId. Can you please check on your hosts whether your configuration complies with [1]. Please check the documentation from this section onwards: "Cluster hosts must not use aliases, either in /etc/hosts or in configuring DNS. A properly formatted /etc/hosts file should be similar to the following example:"   "Null value(s) passed to lookup by non-nullable natural id" is usually thrown because the hosts don't have any resolvable hostnames. All "hostname" values in the list of hosts should also contain the FQDN.   Please let me know if it helped you to alleviate the issue.

Hello @5sdba ,   thank you for reporting the issue you hit. Can you please specify the CDP version you are using and if you are using CM HA (Cloudera Manager High Availability), please?   Thank you: Ferenc ... View more

Hello @HV_Training ,   thank you for reaching out to Community with your question on how to check whether HDFS is started.   Can you please clarify what do you exactly consider "HDFS is fully started"?   If we are happy with an active NameNode as a "HDFS service started" state, I would use the CM API to find out if I already have an active NameNode by a REST call: https://archive.cloudera.com/cm6/6.3.0/generic/jar/cm_api/apidocs/json_ApiNameservice.html   Please let us know if it covers your inquiry.

Hello @Devink ,   thank you for reaching out to the Community.   I understand that your issue is: Hive on Tez job that is failed because of OutOfMemory issue is reported as successful and you would like to know the reason for it.   Please note if you have a Cloudera Subscription, a Support Case might be a better forum for deep analysis.   Could you please give us some additional information, so we can assist you more efficiently? What is the distribution you are using and what is the version number, please? (e.g. HDP, CDH, CDP) Is the successful-state reported via Hue from an Oozie workflow? What Oozie action did you use to execute the Hive job, please? If it is not via Hue and Oozie, please specify where did you see the application reported as successful.   Please note, Oozie is at the mercy of the status reported back from the job it is running.  There are two ways that Oozie can detect a failure in e.g. a Java action. If an exception is thrown from the main method of the class executed by the Java action or System.exit is called anywhere in the code, Oozie will treat the action as failed. It will then transition to the Error state configured for the action.   Thank you: Ferenc   ... View more

Hello @iEason8 ,   Thank you for your observation on the API returns 404 when a request was sent to CM API without authentication.   Based on W3C recommendation about authentication: "... If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead."   Therefore it is OK to return 404 when there is an unauthenticated request and it is a design decision.   Kind regards: Ferenc     ...
