Hi, I'm referring this below article; https://community.cloudera.com/t5/Community-Articles/Create-Dynamic-Partitions-based-on-FlowFile-Content-Convert/ta-p/248367 I'm trying to create pipeline in nifi while data coming realtime streaming based say some example kafka, while data put in hdfs in partitioned location, it may ended be with many small files at the same while querying im facing performance lag issue; can you please give some apporaches to resolve small files issue in nifi itself with orc file format;

Hi @hegdemahendra Thanks for the reply. Based on no of incoming flow files. first time incoming file 1 next time incoming file may be 2 or more than.

Hi, Im currently merge content processor with avro files, data will be coming streaming manner, we want to merge with existing file with new file. While i set minimum no of entries as 2 Is there any possiblities to set minimum no of entires as dynamic manner (dynamic no of input flow files).. Can you please help me out.

@MattWho Thanks for the reply. Sure here i have attached my existing merge_content processor configuration and single node ec2 with 8GB of RAM. can you please clarify if flowfile size gets increase even TB's of data shall i processed with same approach multiple merge_content processor or if it is good with multi-node or increase single node maximum memory availability. JVM Configuration : # JVM memory settings java.arg.2=-Xms2048m java.arg.3=-Xmx2048m

Hi, I'm currently using merge_content processor as merge avro files from two sources like kafka_consumer processor and fetchHDFS file. While converting avro file into one with merge content processor yesterday around 680MB trying to convert but processor drop the file and join with new files and i can't able to recover that data also, because content_repository backup i limit. Can you please help me out for this use_case processor how much size can be good or is there any setting needs to modifiy in nifi.properties.

Hi, We are currently use single node nifi server on aws ec2 instance, We are planning to move multi node cluster architecture. We are in development and testing stage. We need to setup as acvtive and passive nodes, which nifi should works fine whenever one of the server goes down another will pick. can anyone help us to move forward this scenerio or could you suggest any reference architure,

Sure thanks. @MattWho. it works!

Hi, We are currently using merge content processor to merge kafka messages with "minimum number of entries" = 500. when 500 messages reached it will merge as single file. That use case works fine. whenever end of the day at 11:59, is there any queue pending in merge content processor of kafka messages needs to dynamically pushed before start to the new date. Kindly help me out from this kind of use case. Workflow : kafka_consumer -> merge_content_prcessor -> puthdfs @mburgess

Hi, I had been automate get request based on user query param using nifi with help of InvokeHttp.Here is the example; http://aaa.com/q="bigdata"&api_key="" http://aaa.com/q="apple"&api_key="" I did split text using line by line read and invoke http processor using fetch those response as json format. My question is before invokehttp processor, i want to extract those query param values those query values are static. I need to know which query param using i got response. Please give me some suggestion. It would much helpful. Thanks.

@Matt Clarke I don't know which method using fetch Google results either Json/xml format. I'm asking is there any processor available to fetch Google results based on users keywords like Twitter processor.

varun_rathinam · ‎01-24-2018

Hi, I'm working on nifi in hdp 2.5. There is a new requirement normally user entered query/keywords in google and fetch those results either json/xml data format. I need to automate those process, But i didn't able to automate fetch google reuslt using Nifi. Is it possible to do or is there any ways to fetch results like web scrapping instead of programming with help of Nifi. Thanks.

I'm using HDP 2.5. The zeppelin service running successfully, when i create a zeppelin notebook with sample data, For eg; list of data available like this below; id name specialisation city state 001 xxx Android Bronx NY 002 yyy ROR Rome NY 003 zzz IOS Bronx NY 004 ppp Bigdata Dallas TX 005 qqq Android Dallas TX In pie chart is display list of states by using below query %sql select state,count(1) AS states from sample_data where state!='' GROUP BY state ORDER BY states DESC In sqltable is display list of column by using using below query; %sql select id,name,specialisation,city,state from sample_data My question, When i select particular state from this pie chart, For eg TX, The sql table is automatically filtered with selected portion of pie chart.

Hi, I'm using HDP 2.5. I'm beginner into this zeppelin notebook. I have been worked in hue,banana,kibana dashboard. Those dashboards have more dynamic data changes in every widgets like pie,table,map,bar chart. My question is how to i implement like these feature in zeppelin notebook. For eg, if click pie chart one portion it will affect entire notebook. Please tell me how to use zeppelin notebook more effective like this above dashboards and tell me any reference liks.
