Hi @Hamid Zorgani, Thanks a lot for the detailed information. It's really helpful. I have couple of doubts could you please clarify, 1. Do we need to execute all steps in Ambari server? especially from step 1 to 10? 2. I have OpenLDAP installed already in my in cluster, even are also all steps mandatory? Please let me know if you need any more information. Regards, Manjunath P N

@Jay Kumar SenSharma, Thank you for your inputs. After running yum install commands the outcome will be krb5.conf file and i am already having the same file structure in my repository so can I directly go ahead with enabling Kerberos via Ambari and does the conf file will accept this? Regards, Manjunath P N

Hi @Jay Kumar SenSharma, Thank you for your inputs. When I am trying to install Kerberos using "yum install krb5-server krb5-libs krb5-workstation" it is failing to install with below error messages. https://fedora-mirror.zerocopy.io/epel/7/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed connect to fedora-mirror.zerocopy.io:443; Connection refused" Trying other mirror. http://mirror.de.leaseweb.net/epel/7/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed to connect to 2a00:c98:2030:a034::21: Network is unreachable" Trying other mirror. http://ftp.uni-stuttgart.de/epel/7/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed to connect to 2001:7c0:2041:8::112: Network is unreachable" Trying other mirror. http://mirror.23media.de/epel/7/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed to connect to 2a00:f48:1007::80: Network is unreachable" Trying other mirror. https://mirror.imt-systems.com/epel/7/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed to connect to 2a01:7e0:0:201::10:20: Network is unreachable" Trying other mirror. ^Chttp://fedora.tu-chemnitz.de/pub/linux/fedora-epel/7/x86_64/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for epel: Damaged repomd.xml file Trying other mirror.

@Geoffrey Shelton Okot, @mthiele, I want to install Kerberos on Hadoop cluster, i have seen the article Configuring Ambari and Hadoop for Kerberos using AD as the KDC - Video https://community.hortonworks.com/questions/103945/kerberos-setup-on-hdp-26.html and this is really helpful. I have couple of questions on this, 1.Do I need to install Kerberos via command line before starting this task? 2. Because i see krb5.conf file exists in my cluster and kerberos is not enabled, do I need to delete the conf files in all nodes and run"yum install -y krb5-server krb5-libs krb5-workstation" command then carry on the steps provided in the aboe article or i don't need to bother to about and straightaway start from Ambari for enabling process. 3. As per the official doc. https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.5/bk_security/content/configuring_amb_hdp_for_kerberos.html we need to enable Kerberos from Ambari, Now i need a clear idea 1st do I need to install kerberos using yum command and then start enabling from Ambari.?? Best Regards and Thanks in advance, Manjunath P N

Hi @mthiele, One quick question: Does ambari server and all other datanodes will have krb5.conf file by default? or it will be available under /etc folder only after we enabling kerberos via ambari? Because when I see in our prod env. krb5.file is available even though we did not enable. If yes, after Configuring KDC in Ambari does it change the conf for all nodes? Regards, Manjunath P N

HI All, can somebody let me know which version of HDP supports Spark 2.4? and is that good idea to go to Spark 2.4 instead of 2.3? My Current versions: HDP 2.6.3.0 Apache Ambari 2.6.0.0 HDFS 2.7.3 YARN 2.7.3 MapReduce2 2.7.3 Spark2 2.2.0 Any suggestions are welcome. Regards, Manjunath P N
