Twitter sentiment analysis using Hive

Twitter is one of the most important data sources that helps you to know the sentiments behind various things. In this recipe, we will take a look at how to perform sentiment analysis using Hive on Twitter data.

hadoop fs -mkdir /data
hadoop fs -put tweets_raw /data
hadoop fs -put time_zone_map /data
hadoop fs -put dictionary /data

We use Hive's JSON SerDe jar to read the tweeter data, as shown here:
