Accessing public social data from Facebook for a company's page is easy.
Find your Facebook page, say Hortonworks.
Run http://findmyfbid.com/ and get the Page ID (289994161078999) for your Page.
Create a Facebook Application and Add a New Application.
Create a Facebook Access Token in Graph API Explorer using your Application.
Create your Facebook Graph API URL. https://graph.facebook.com/v2.7/289994161078999/tagged?access_token=ACCESSTOKENFROMFACEBOOK&limit=10.... Because we are using a Facebook App Token, we need to use HTTPS/SSL. To access an SSL site in GetHTTP, we need a SSL Service with a Trust Store.

Add the URL to the GetHTTP Processor.
Create a Standard SSL Context Service (Controller Service), for the Sandbox, use the Java SSL Trust Store.
Add the SSL Context Service to the GetHTTP Processor.
Save to HDFS (PutHDFS).

Crunch Big Data Conference 2016\nCASEY STELLA - Principal Architect of
Hortonworks \nTalk: Data Preparation for Data Science: A Field
Guide\n\n\"Any data scientist who works with real data will tell you that
the hardest part of any data science task is the data preparation. Everything
from cleaning dirty data to understanding where your data is missing and how
your data is shaped, the care and feeding of your data is a prime task for the
working data scientist.\n\nI will describe my experiences in the field and
present an open source utility written with Apache Spark to automate some of
the necessary but insufficient things that I do every time I'm presented new data.
In particular, we'll talk about discovering missing values, values with skewed
distributions and discovering likely errors within your data.\"\n\nSee you
at Crunch Big Data Conference in 2016!\n#bigdata #dataanalytics #crunchconf
