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 . |

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. |
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)|...|(VISN) . |
