@Mondi    KMS service should be installed on your CDH cluster. Before installing KMS, you should have a dedicated cluster added using the Cloudera manager Add Cluster option which has the KTS service roles installed.   If you are installing default Hadoop KMS Java Keystore KMS, the above can be ignored since the default Hadoop KMS included in CDH uses a file-based Java KeyStore (JKS) for its backing keystore. You can simply add the service from Cloudera Manager.  Cloudera strongly recommends that you enable TLS for both the HDFS and the Key Trustee KMS services to prevent the passage of plain text key material between the KMS and HDFS data nodes.   Refer below document  https://docs.cloudera.com/documentation/enterprise/latest/topics/sg_hdfs_encryption_wizard.html#concept_fcq_phr_wt   Hope this helps, Paras Was your question answered?

@fransyk    It is not compulsory to have both the roles on different hosts.  Having said that, in production environments it is recommended to differentiate worker hosts and master hosts.   Please refer below document for recommended role allocations for different cluster sizes:   https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_ig_host_allocations.html#concept_f43_j4y_dw   Hope this helps, Paras Was your question answered?

@fransyk    Yes, you can have datanode and namenode role together on a host as long as the hardware requirements are met for the service to avoid any out of memory issues.   Please refer  https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_hardware_requirements.html#concept_fzz_dq4_gbb   Hope this helps, Paras Was your question answered?

@pdev    Please refer document [1] for details on how to enable replication between cluster with kerberos configuration. To configure encryption of data transmission between source and destination clusters: Enable TLS/SSL for HDFS clients on both the source and the destination clusters.  You may also need to configure trust between the SSL certificates on the source and destination. The certificates of the source cluster should be trusted by your destination cluster. Enable TLS/SSL for the two peer Cloudera Manager Servers.  Refer link [2] for more details.   [1] https://docs.cloudera.com/documentation/enterprise/5-14-x/topics/cm_bdr_replication_and_kerberos.html#xd_583c10bfdbd326ba-5676e95c-13ed333c3d9--7ff3   [2] https://docs.cloudera.com/documentation/enterprise/5-14-x/topics/cm_bdr_replication_and_encryption.html#concept_lrr_rcf_4r   Hope this helps, Paras Was your question answered?

@rok    You can use the Cloudera Manager REST API to export and import all of its configuration data. The API exports a JSON document that contains configuration data for the Cloudera Manager instance. You can use this JSON document to back up and restore a Cloudera Manager deployment.   Refer below document for the steps: https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_intro_api.html#concept_dnn_cr5_mr   Hope this helps, Paras Was your question answered?
