@shraddha srivastav Based on the logs now i see that your Zeppelin is listening properly to port 8888 without any issue. have you accessed Zeppelin using browser after "2019-06-13 01:11:27" time ? INFO [2019-06-13 01:11:27,800] ({main} AbstractConnector.java[doStart]:292) - Started ServerConnector@234cd86c{HTTP/1.1,[http/1.1]}{0.0.0.0:8888}   INFO [2019-06-13 01:11:27,801] ({main} Server.java[doStart]:407) - Started @8727ms   INFO [2019-06-13 01:11:27,807] ({main} ZeppelinServer.java[main]:249) - Done, zeppelin server started So if you are still not able to access the Zeppelin UI via browser then it might be some proxy/firewall issue. Can you please try running the following command from two hosts: 1. Run the curl command from host where you are running your browser to access Zeppelin UI: # curl -iv  http://$ZEPPELIN_HOSTNAME:8888 2. Now login to Zeppelin host and then try running the same curl call with "localhost" and hostname. # curl -iv  http://$ZEPPELIN_HOSTNAME:8888 # curl -iv  http://localhost:8888 Please share the *complete* output of both the Calls. Also please check if the "iptables" (firewall) is disabled on your Zeppelin server host or not? ... View more

@Vivek Singh Once the Blueprint based cluster deployment begins then we do not have much control to change anything during that period of cluster creation. However if you are noticing that some of the hosts are keep showing the OUT_OF_SYNC HostStackVersions then there may be some binary packages already installed on those hosts or the host cleanup might not be performed on those hosts prior to upgrade. Or was the Ambari DB Clean prior to the blueprint based cluster setup? However if we want to know exact reason on why the HostStackVersions is changing to OUT_OF_SYNC then it will require some investigation. Like following: 1. Checking the whole ambari-server.log (during blueprint based cluster deployment) 2. Checking the complete ambari-agent.log on the hosts where the installation is failing. 3. Was the Ambari DB Clean prior to the blueprint based cluster setup? ... etc 4. It might be also a good odea to check the blueprint.json and clustermaping.json file. With exact Ambari API commands to find out if any thing is wrong there. ... View more

@shraddha srivastav Yes, if you change the port of your zeppelin to some other port which is free then it should work. Or you will need to stop the other process which is using that port 8090 to avoid port conflict. ... View more

@Jayashree S For inserting JSON data to Database you can refer to the ConvertJSONToSQL processor. This processor converts simple JSON into an SQL INSERT statement that will allow a relational database to be populated with the JSON data. It Converts a JSON-formatted FlowFile into an UPDATE, INSERT, or DELETE SQL statement. The incoming FlowFile is expected to be "flat" JSON message, meaning that it consists of a single JSON element and each field maps to a simple type. A good explanation of it can be found in the following HCC thread: https://community.hortonworks.com/questions/139219/convert-json-to-sql-format.html .
