 <p>Pig has two execution modes or exectypes: </p>
 <ul>
-<li><strong>Local Mode</strong> - To run Pig in local mode, you need access
to a single machine; all files are installed and run using your local host and file system.
Specify local mode using the -x flag (pig -x local).
+<li><strong>Local Mode</strong> - To run Pig in local mode, you need access
to a single machine; all files are installed and run using your local host and file system.
Specify local mode using the -x flag (pig -x local). Note that local mode does not support
parallel mapper execution with Hadoop 0.20.x and 1.0.0. This is because the LocalJobRunner
of these Hadoop versions is not thread-safe.
 </li>
 <li><strong>Mapreduce Mode</strong> - To run Pig in mapreduce mode, you
need access to a Hadoop cluster and HDFS installation. Mapreduce mode is the default mode;
you can, <em>but don't need to</em>, specify it using the -x flag (pig OR pig
-x mapreduce).
