@vincentD The CM agents should be able to send hearbeats to the CM sever successfully before the parcel installation. Did you also happen to setup TLS here? Please check the CM server and agent logs on the nodes for issues reported. Click on the hostnames what is the error reported on Cloudera Manager for the hosts?

@michaelli You can use the CM API to fetch the service configurations by executing below command from terminal # curl -u admin_uname:admin_pass "http://cm_server_host:7180/api/v19/cm/deployment" The password should be present under the name : hive_metastore_database_password Refer: https://docs.cloudera.com/documentation/enterprise/5-14-x/topics/cm_intro_api.html#concept_dnn_cr5_mr__section_ztf_lyt_xr Hope this helps, Paras Was your question answered?

@Siddo You can migrate the Hue DB. Refer doc to migrate Hue DB https://docs.cloudera.com/documentation/enterprise/6/latest/topics/hue_dbs_migrate.html#hue_dbs_migrate Manually migrating queries from tables would be complex and not tested completely. It has the below requirement: The Hue database has a "desktop_document2" table that stores all the saved queries and Oozie workflows and all sorts of users' saved stuff (query history included). This table has an OWNER_ID column that is a foreign key to the auth_user table's ID column. The process of getting the new ID of the "auth_user" table, and associating them with the correct "owner_id" in the "desktop_document2" table, can be very involved.

@Siddo Do you mean saved queries are not available in hue 4 but present in hue 3.9 version? Have you recently upgraded the cluster? What is the CDH version here? Go to "http[s]://<huehost>:<hueport>/home" or click the house icon in the upper left corner in hue. After this recheck if the saved queries are visible.

@sow What is the mysql DB version being used here? Does this only support TLSV1 ? You should consider upgrading the DB to the latest supported TLS versions. TLSV1 is included in the disabled algorithms in the latest java versions by default . The option of disabling the algorithms from java.security hence works in the particular host once you update the java.security file. This is the only workaround here but not recommended since TLSv1 is deprecated. Ref: https://dev.mysql.com/doc/refman/5.7/en/encrypted-connection-protocols-ciphers.html

@sow Sqoop does not currently support TLS/SSL to Oracle, MySQL, or other databases. Refer:https://docs.cloudera.com/documentation/enterprise/5-14-x/topics/cm_sg_hadoop_ssl_cm.html

@had00p101 To allow scheduler access, please uncheck the permission disable_editor_access if this is enabled for the hue user group. Only oozie.access, oozie.dashboard_jobs_access is required to be set under the group permissions set for user in Hue. Hope this helps, Paras Was your question answered?

@chhaya_vishwaka The "ERR_SSL_VERSION_OR_CIPHER_MISMATCH" error can happen if a JKS contains multiple certs with similar names. Run below command for the keystore # keytool -list -keystore server.jks The correct cert with be the one with "Entry type: PrivateKeyEntry". If you find a certificate with "Entry type: trustedCertEntry" and a similar alias name then that is the problem cert. Remove this certificate from keystore using below steps: i) Make a backup of the existing JKS. ii) Stop CM iii) Remove the cert identified above. keytool -delete -alas <cert_alias> -keystore server.jks iv) Start CM and test again.
