@Prakash Punj As we see the error which shows that due to SSL issue amabri agent is not able to communicate with ambari server. IOError: Request to https://ambari.asotc.com:8441/agent/v1/register/ds.asotc.com failed due to <urlopen error EOF occurred in violation of protocol (_ssl.c:661)> ERROR 2018-04-24 10:55:27,949 Controller.py:227 - Error:Request to https://ambari.asotc.com:8441/agent/v1/register/ds.asotc.com failed due to <urlopen error EOF occurred in violation of protocol (_ssl.c:661)> So can you please try adding the following option to security section in "/etc/amabri-agent/conf/ambari-agent.ini" in all the hosts in the cluster [security] force_https_protocol=PROTOCOL_TLSv1_2 For more information on thjis please refer to: https://community.hortonworks.com/questions/114808/ambari-agents-cannot-reach-ambari-server-after-cha.html . ...

@Victor HDP and HDF are separate products and they include different set of components. HDP Shipped components: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_release-notes/content/comp_versions.html HDF Shipped Components: https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.1/bk_release-notes/content/ch_hdf_relnotes.html So based on your requirement you can choose any of those distributions. It is also possible to have the HDF components installed on an existing HDP cluster as described in : https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.1/bk_installing-hdf-on-hdp/content/upgrading_ambari.html . There are some types of Sandboxes available for download and use. Like HDP Sandbox & HDF Sandbox so you can shoose then based on your interest and requirement. Those different types of Sandbox Downloads can be found here: https://hortonworks.com/downloads/#sandbox . ... View more

@Kumar Veerappan Please use the Escape characters (\\) when specifying the | (pipe) sign as following: Like : -Dhttp.nonProxyHosts=aaa.com\|bbb.com\|ccc.com Example: # grep AMBARI_JVM_ARGS /var/lib/ambari-server/ambari-env.sh export AMBARI_JVM_ARGS=$AMBARI_JVM_ARGS' -Xms512m -Xmx2048m -XX:MaxPermSize=128m -Djava.security.auth.login.config=$ROOT/etc/ambari-server/conf/krb5JAASLogin.conf -Djava.security.krb5.conf=/etc/krb5.conf -Djavax.security.auth.useSubjectCredsOnly=false -Dhttp.nonProxyHosts=aaa.com\|bbb.com\|ccc.com' .

@Kumar Veerappan Please check the following things on all your hosts 1. Check if the "iptables" or "firewall" is disabled on all hosts. 2. As the alerts scripts are executed from different hosts of the cluster nodes Hence please make sure that every host of your cluster is able to resolve each others address and able to access the mentioned Hostname & Ports. # telnet node1.dev.XXXXXXXX.io 50075 # telnet api1.dev.XXXXXXX.io 8088 3. Also on the hosts where the DataNode and Resource Manager Ports are supposed to be listening , Please check if they are actually listening and Bound to correct IPAddress and correct interface (ip address)? # netstat -tnlpa | grep 8088 # netstat -tnlpa | grep 50075 . 4. Also please check if you have installed any HTTP Proxy on your machines (cluster nodes) ? Which might be restricting the access of those URL endpoints. Like http_proxy, So better to check if you are able to access the mentioned URL from any node of the cluster using curl without any issue or not? # curl http://node1.dev.XXXXXXXX.io:50075 # curl http://api1.dev.XXXXXXX.io:8088 . ...
