@Davide Isoardi Good Afternoon, sir. May i ask you something ? Is http://www.ecubecenter.it/Hadoop-Big-Data-Twitter-Map/ using this https://github.com/disoardi/tweetsdemo_with_ambari_views. It has been a while that i lost my mind to work my undergraduate project. Maybe, i will start again from this. Thanks before ... View more

@Ravi Mutyala Hmmm..., I dont know if there are more tutorial about Apache Nifi in this forum than Hortonworks Tutorial. Better to check it, and thanks a lot. ... View more

@Pierre Villard I want to send Twitter username from smartphone to HDP. When ListenHTTP get the data, it will send to GetTwitter to get some tweet according username. After that, i will use spark to calculate Machine Learning Algorithm to predict user personality. ... View more

@Kirk Haslbeck Thanks, i will try it, one of them as fast as possible ... View more

Hmmmm, so the key of this is Apache Nifi. In Nifi, we can create a sequence from get the data, process it and save it according the Processor what we choose. If in the first time, i can load "aloha.csv" and make a table from it manually (Click Files Views and Hive View). So, with Nifi i can load "aloha.csv" and make a table automatically using the Processor. Is it correct ? Well, maybe i try it. I'm sorry if i ask too much because i need to clarify this. Because, if i cant implement this (my final project in the college), i will step back to search another idea. ... View more

@Davide Isoardi Thanks for reply my question. But, i have another question. When an App using web service, the sequence will be like this. Android --[JSON Data]--> Web Service --[SQL Query]--> Database. In this case, to proccess the data, we only using Web Service and send SQL Query to Database. From the your answer this is what i get. Android --[Twitter Data]--> Nifi --> Solr --> Spark --> Another Solr Collection --[JSON Format]--> Android In this case, to process the data we need many app to send data. From Android to Nifi, from Nifi to Solr, etc. Can Solr receive data from Nifi after that send to Spark ? Because i never know how to communicate (send/receive data) from one app to another app in HDP automatically like your idea ? I'm sorry, if my question makes you confuse 😉 ... View more
