Re: Text Analysis
Hadoop itself is the core Map/Reduce and HDFS functionality.  The higher level algorithms like sentiment analysis are often done by others.  Cloudera has a video from HadoopWorld 2010 about it


And there are likely to be other tools like R that can help you out with it.  I am not really sure if mahout offers sentiment analysis or not, but you might want to look there too http://mahout.apache.org/

I wanted to know if there are any existing API's within Hadoop for us to do some text analysis like sentiment analysis, etc. OR are we to rely on tools like R, etc. for this.
