@James Srinivasan As per supportmatrix when you click on HDP 3.1 in the following link then you will find only the following versions of Postgres supported (tested & certified) with HDP 3.1 (Means components used by HDP 3.1) Postgres: 10.2 And 9.6 . Similarly in Support matrix if you select only Ambari 2.7 (like 2.7.1/ 2.7.3) then you will find the postgres version as : Postgres: 10.2 And 9.6 . Hence while planning for an Upgrade (Ambari + HDP) you should also plan for upgrading the Postgres DB to the tested and certified version of Postgres. . Yes you are correct upgrading Postgres is not handled by ambari. Hence you will need to make sure that you take a backup (DB dumps) of your current postgres 9.2 DB and then perform the Postgres DB upgrade separately.

@Michael Bronson It will be good to first isolate if the issue is from Ambari Side or from Kafka side. Which can be done by tring to start the kafka broker manually using command line to see if it starts fine or not? # su $KAFKA_USER # /usr/hdp/current/kafka-broker/bin/kafka start . If kafka broker starts successfully this way then there might be some issue in the way we are starting kafka from Amabri. We will have to look into the "ambari-server.log" or "ambari-agent.log" of that time also looking at the Ambari UI operation log of kafka startup operation will be useful. May be restarting ambari agent. . If kafka is not even starting from command line then we will have to review the kafka broker logs. Can you also verify if the property changes are present on the kafka config on the individual host like: # grep 'log.retention.hours' /etc/kafka/conf/* /etc/kafka/conf/server.properties:log.retention.hours=24 .

@Divya Thaore Looks like you are running Oracle 10g database on your localhost. Oracle 10g DB also uses port 8080 as default port. Please stop Oracle Database and then you should be able to access Ambari port 8080 if needed please restart your Sandbox after stopping Oracle Database on your laptop.

@Divya Thaore Please share the screenshot where you see the popup. Also is there any specific reason that you are using Ambari 2.2.0 ( as we see this tag in your HCC post) that is too old version of ambari and you should rather use latest ambari. . Check your Browser to verify if it has a JRE installed to it and if it is it bit old needs update? Please refer to the following link to know which JRE is installed to your browser and if it is up to date?

@rakesh m I do not see that Oracle Linux 5.6 in the Tested and Certified version os OS with HDP3 Please check : https://supportmatrix.hortonworks.com/ It will be good to be on the tested and certified version of OS.

@rakesh m You can install this package from OS repo in following ways as they come as Optional-rpms of rhel-server repositories: Option-1. Enable the Optional rpm's for rhel-server # yum-config-manager --enable rhui-REGION-rhel-server-optional # yum install libtirpc-devel Option-2. Download the package(quick way) and install on all the hosts, (following is just an example you might have slightly different version of RHEL) Internet Access # yum install https://www.rpmfind.net/linux/centos/7.5.1804/os/x86_64/Packages/libtirpc-devel-0.2.4-0.10.el7.x86_64.rpm - If No internet access, then you can download on you machine then put it on server and execute below command # yum localinstall libtirpc-deve* .

@rakesh m You will see the error as following: RuntimeError: Failed to execute command '/usr/bin/yum -y install hadoop_3_1_0_0_78-yarn', exited with code '1', message: 'Error: Package: hadoop_3_1_0_0_78-hdfs-3.1.1.3.1.0.0-78.x86_64 (HDP-3.1-repo-1) Requires: libtirpc-devel HDP package has a dependency to "" package This package you can find from the Base repo of your OS. Please see a similar discussion here and install the "libtirpc-devel" on your cluster nodes prior to installing the components. https://community.hortonworks.com/questions/109996/hdp-26-requires-libtirpc-devel.html

@Leonardo Araujo The Sandbox is a docker container runs inside the VM. So if you want to login to login to the VM where the Docker container is started then you will need to use the SSH Port 2122 But if you want to actually login to the Sandbox Docker container where the HDP components/services are present then you will need to do SSH on port 2222 . You will find the Sandbox Port mapping info here: https://hortonworks.com/tutorial/hortonworks-sandbox-guide/section/3/ Sandbox Architecture: https://hortonworks.com/tutorial/sandbox-architecture/
