 +This example archives file data into an Accumulo table.  Files with duplicate data are only
stored once.
 +The example has the following classes:
 +
 + * CharacterHistogram - A MapReduce that computes a histogram of byte frequency for each
file and stores the histogram alongside the file data.  An example use of the ChunkInputFormat.
 + * ChunkCombiner - An Iterator that dedupes file data and sets their visibilities to a combined
visibility based on current references to the file data.
 + * ChunkInputFormat - An Accumulo InputFormat that provides keys containing file info (List<Entry<Key,Value>>)
and values with an InputStream over the file (ChunkInputStream).
 + * ChunkInputStream - An input stream over file data stored in Accumulo.
-  * FileDataIngest - Takes a list of files and archives them into Accumulo keyed on the SHA1
hashes of the files.
-  * FileDataQuery - Retrieves file data based on the SHA1 hash of the file. (Used by the
dirlist.Viewer.)
++ * FileDataIngest - Takes a list of files and archives them into Accumulo keyed on hashes
of the files.
++ * FileDataQuery - Retrieves file data based on the hash of the file. (Used by the dirlist.Viewer.)
 + * KeyUtil - A utility for creating and parsing null-byte separated strings into/from Text
objects.
 + * VisibilityCombiner - A utility for merging visibilities into the form (VIS1)|(VIS2)|...
 +
 +This example is coupled with the dirlist example.  See README.dirlist for instructions.
 +
 +If you haven't already run the README.dirlist example, ingest a file with FileDataIngest.
 +
 +    $ ./bin/accumulo org.apache.accumulo.examples.simple.filedata.FileDataIngest -i instance
-z zookeepers -u username -p password -t dataTable --auths exampleVis --chunk 1000 $ACCUMULO_HOME/README
 +
 +Open the accumulo shell and look at the data.  The row is the MD5 hash of the file, which
you can verify by running a command such as 'md5sum' on the file.
 +
 +    > scan -t dataTable
 +
 +Run the CharacterHistogram MapReduce to add some information about the file.
 +
 +    $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.filedata.CharacterHistogram
-i instance -z zookeepers -u username -p password -t dataTable --auths exampleVis --vis exampleVis
 +
 +Scan again to see the histogram stored in the 'info' column family.
 +
 +    > scan -t dataTable
