@saihadoop I am little bit unsure what LDAP config file you wants to see. Though to answer you question which services can support LDAP mechanism in CDH you can see the doc below.  https://docs.cloudera.com/documentation/enterprise/latest/topics/sg_auth_overview.html#concept_fjp_ht_bt Few components is like: - Cloudera Manager - Cloudera Navigator Metadata Server - Hue - Hive - Impala - Solr   Also to check configuration related with LDAP in CDH services you can just go to service > Configuration > From Category select External Authentication. Here you can see all LDAP related parameters. ... View more

@Rah It's worth to check if you have TLS enabled installation. I see a note in doc which needs out attention. If you have enabled Auto-TLS, you must include the Cloudera Manager server host when you specify hosts.  https://docs.cloudera.com/cdpdc/7.0/installation/topics/cdpdc-install-runtime-using-wizard.html   Did you restart CM after disabling TLS? Also, when you are using the add host wizard, you do not want to set use_tls=1 until the host is successfully added. It is actually kind of a messy procedure: 1. Disable Use TLS Encryption for Agents, and Use TLS Authentication of Agents to Server. 2. Restart CM 3. Add host to CM 4. Turn on Use TLS Encryption for Agents, and Use TLS Authentication of Agents to Server. 5. Configure agent to use TLS (setting use_tls=1 and the cert/key parameters, or copy config.ini from another host with TLS enabled). 6. Restart agent Alternatives: Use Auto-TLS introduced in C6 Follow the "Alternate Method of installing Cloudera Manager Agent without Disabling TLS" steps instead. If above does not help then we need full log file from CM server to take a look.   Cheers, ... View more

@Pankaj276356   The Cloudera Quick start VM has been discontinued as It was based on CDH 5.13 which is going end of support in the Fall of this year.   As we have introduced CDP so it's available to taste and to get you experience new exciting feature of it.  Also you can try an docker image of Cloudera available publicly on https://hub.docker.com/r/cloudera/quickstart or simply run below command to download this on docker enabled system.  docker pull cloudera/quickstart NOTE: Cloudera Don't support QuickStart VM Officially.  ...

@thuylevn I found this somewhere you can try this.   You could do this using the   docker-machine mount   command. Using this command,you can mount directories from a machine to your local host, using sshfs. The notation is machinename:/path/to/dir for the argument; you can also supply an alternative mount point (default is the same dir path). consider an example: $ mkdir foo $ docker-machine ssh dev mkdir foo $ docker-machine mount dev:/home/docker/foo foo $ touch foo/bar $ docker-machine ssh dev ls foo bar Now you can use the directory on the machine, for mounting into containers. Any changes done in the local directory, is reflected in the machine too. $ eval $(docker-machine env dev) $ docker run -v /home/docker/foo:/tmp/foo busybox ls /tmp/foo bar $ touch foo/baz $ docker run -v /home/docker/foo:/tmp/foo busybox ls /tmp/foo bar baz The files are actually being transferred using sftp (over an ssh connection). ...

@P_Suresh_Rao The reason on your ask is as per my guess is that QuickStart VM don't have internet access.  If yes then you can download packages externally and then copy into QuickStart and install something like: $ sudo yum update $ sudo yum install yum-utils You can then install the CentOS IUS package which will get you up to date with their site: $ sudo yum install https://centos7.iuscommunity.org/ius-release.rpm Finally you can then install Python and Pip: $ sudo yum install python36u $ sudo yum install python36u-pip If the QuickStart have internet access then you can just update Python like any other packages with yum update command. https://developers.redhat.com/blog/2018/08/13/install-python3-rhel/ ...

@CaptainJa  The version of Tomcat used in CDH 5.16.2 should not have any vulnerabilities. Could you share the CVE that is reported CDH is vulnerable to?   Per the notice [1] independent upgrade of Tomcat is not supported and we are moving towards newer versions in CDH6 => Cloudera Enterprise 6 has replaced Tomcat 6 with Jetty 9 and is not susceptible to Tomcat security issues.   LINKS: [1] https://community.cloudera.com/t5/Customer/CDH-5-support-for-Tomcat-6/ta-p/73655 ...

@SVK NO. Airflow is not a part of the Cloudera suite of application. While you can definitely use 3rd party CSDs in general [1], or make your own CSDs, the support of it is outside Cloudera's scope. If you do pursue to install, my suggestion is to install in a dev/test environment and test it out. Once you are comfortable with the product then you can install into your production cluster.   Again this is not under Cloudera Support's Scope.  Feel free to reach out to your accounts team if you need more information about Cloudera's offerings.   [1] https://github.com/teamclairvoyant/apache-airflow-cloudera-csd ...

@asmarz You don't have to create every user manually. This can be taken care by Ambari itself. Our doc says: When you enable Kerberos, if you choose to use an  Existing MIT KDC  or  Existing Active Directory , the Kerberos Wizard prompts for information related to the KDC, the KDC Admin Account credentials, and the Service and Ambari principals. Once provided, Ambari will automatically create principals, generate keytabs and distribute keytabs to the hosts in the cluster. The services will be configured for Kerberos and the service components are restarted to authenticate against the KDC. This is the  Kerberos Automated Setup  option.   Please follow below doc for this: https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.5/bk_security/content/_managing_admin_credentials.html   https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.5/bk_security/content/_use_an_existing_active_directory_domain.html ...
