. MapReduce is free to select a node that includes a copy of a shard/block of dataThe input shard is a logical division, and the HDFS data block is the physical division of the input data. When they are consistent, they are highly efficient. In practice, however, there is never a complete agreement that records may cross the bounds of a block of data, and a compute node that processes a particular shard gets a fragment of the record from a block of data Hadoop learning; Large

The previous three posts have been a fairly complete feature engineering, analyzing string-type variables to get new variables, normalize numeric variables, get derived properties and make dimensional specifications. Now that we have a feature set,
which Classifier is should I Choose?
This is one of the most import questions to ask when approaching a machine learning problem. I find it easier to just test them all at once. Here's your favorite Scikit-learn algorithms applied to the leaf data.
