/**
 * When isGrouped is true, it specifies that grouping of input splits be
 * performed by Tez The conf should have the input format class configuration
 * set to the TezGroupedSplitsInputFormat. The real input format class name
 * should be passed as an argument to this method.
 * <p/>
 * With grouping enabled, the eventual configuration used by the tasks, will have
 * the user-specified InputFormat replaced by either {@link org.apache.hadoop.mapred.split.TezGroupedSplitsInputFormat}
 * or {@link org.apache.hadoop.mapreduce.split.TezGroupedSplitsInputFormat}
