ChunkCombiner This iterator dedupes chunks and sets their visibilities to the combined visibility of the refs columns.
ChunkInputFormat An InputFormat that turns the file data ingested with FileDataIngest into an InputStream using ChunkInputStream.
ChunkInputStream An input stream that reads file data stored in one or more Accumulo values.
FileDataIngest Takes a list of files and archives them into Accumulo keyed on the SHA1 hashes of the files.
FileDataIngest.Opts
