Method Detail

writeLoadMapping

public static void writeLoadMapping(SortedMap<KeyExtent,Bulk.Files> loadMapping,
                                    String sourceDir,
                                    BulkSerialize.Output output)
                             throws IOException

Serialize bulk load mapping to "loadmap.json"

Throws:

IOException

readLoadMapping

public static LoadMappingIterator readLoadMapping(String bulkDir,
                                                  TableId tableId,
                                                  BulkSerialize.Input input)
                                           throws IOException

Read Json array of Bulk.Mapping into LoadMappingIterator

Throws:

IOException

writeRenameMap

public static void writeRenameMap(Map<String,String> oldToNewNameMap,
                                  String bulkDir,
                                  BulkSerialize.Output output)
                           throws IOException

Writes rename file to JSON. This file maps all the old names to the new names for the BulkImportMove FATE operation.

Throws:

IOException

readRenameMap

public static Map<String,String> readRenameMap(String bulkDir,
                                                     BulkSerialize.Input input)
                                              throws IOException

Reads the serialized rename file. This file maps all the old names to the new names for the BulkImportMove FATE operation.

Throws:

IOException

getUpdatedLoadMapping

public static LoadMappingIterator getUpdatedLoadMapping(String bulkDir,
                                                        TableId tableId,
                                                        BulkSerialize.Input input)
                                                 throws IOException

Read in both maps and change all the file names in the mapping to the new names. This is needed because the load mapping file was written with the original file names before they were moved by BulkImportMove

Throws:

IOException
