### Description of PR
I am looking to add a new map reduce example, i.e, sentiment analysis.
Sentiment analysis map reduce job helps in determining the sentiment score for
a user. It takes each tweet made by an user and assigns a sentiment score for
that tweet/sentence for a particular user and then aggregates the sentiment
scores for all tweets made by all users.
This example takes the twitter dataset which contains users and the tweets
made by users and gives the output as <username, sentiment score>. For each
user, the sentiment score is calculated for all the tweets made by that
particular user.
### How was this patch tested?
This patch was tested using the twitter dataset on a single node Hadoop
cluster in pseudo-distributed mode.
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
