we have seen twitter analysis using Hive at many places, Here I am going to present my way of analyzing tweet's sentiments using Apache Pig. what we want to do ? we want to analyse tweets to check if they contain positive emotions or negative emotions. tweets reflects person's emotions when he or she was posting it like " got this Job done...Hurrahh.." or "xyz Movie sucks!!!! worst movie I ever saw....". what we need ? we need to fetch tweets from twitter to HDFS so that we can do our analysis using Hadoop ecosystem (Apache Pig Here).
