@Mondi    Cloudera provides two implementations of the Hadoop KMS. Refer below document for more details. https://docs.cloudera.com/documentation/enterprise/latest/topics/cdh_sg_kms.html You need to install Key Trustee KMS only when using KTS as backing keystore instead of the file-based Java KeyStore (JKS) used by the default Hadoop KMS.   There should be a separate cluster for keytrustee server. This would be mentioned as one of the steps when you enable HDFS encryption via the wizard.   Refer below document https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/sg_hdfs_encryption_wizard.html#concept_n2p_5vq_vt   Hope this helps, Paras Was your question answered?

@Mondi    You do not need to install Cloudera Navigator for KMS and KTS. Refer : https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/encryption_prereqs.html#concept_g23_454_y5__section_n4w_b5v_ls   Please refer below documents for encrypting data at rest requirement and installing KMS and KTS. You must install Key Trustee Server before installing and using Key Trustee KMS.   https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/encryption_planning.html#concept_c4m_knq_w5 https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/key_trustee_install.html#xd_583c10bfdbd326ba-590cb1d1-149e9ca9886--7b84 https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_ig_install_keytrustee.html#xd_583c10bfdbd326ba-590cb1d1-149e9ca9886--7860   Hope this helps, Paras Was your question answered?

@Mondi  Please refer below document which explains steps to configure jar for UDFs.  You can configure the cluster in one of several ways to find the JAR containing your UDF code, and then you register the UDF in Hive. https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_mc_hive_udf.html#xd_583c10bfdbd326ba--43d5fd93-1410993f8c2--7ea3   Hope this helps, Paras Was your question answered?

@rmr1989    Ideally, for a missing mounts in the cluster you would automatically get alerts for services if any hadoop service directories cannot be accessed which are mapped to the mountpoint. They can be generic though like "no such file or directory" or "file not found" errors.   If you are looking for specific mountpoint availability, you should consider using script to scan for mountpoints in the cluster hosts and can send email alerts using SMTP from the host instead of Cloudera Manager.   Hope this helps, Paras Was your question answered?

@rmr1989    You can edit the expression manually to include the NOT operator. Check the below example which uses NOT operator for a trigger. A trigger expression takes the form: IF (CONDITIONS) DO HEALTH_ACTION   A condition is any valid tsquery statement with below syntax.  SELECT [metric expression]WHERE [predicate]   Mount point is an attribute which can be used in filter conditions but not metric expression. Hence, I believe it would not be possible to create a trigger on mount point scans.   Refer below document which lists the supported metrics: https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_metrics.html#xd_583c10bfdbd326ba--7f25092b-13fba2465e5--7e52   Example:   IF (SELECT total_xceivers_across_datanodes WHERE serviceName=$SERVICENAME AND last(total_xceivers_across_datanodes) != 0 AND entityName = "HDFS-1:ns1" AND category = "SERVICE") DO health:concerning   Hope this helps, Paras Was your question answered?
