> During bootstrap phase it may happen that the files copied to target are
> created by events which are not part of the bootstrap. This is because of the
> fact that, bootstrap first gets the last event id and then the file list.
> During this period if some event are added, then bootstrap will include files
> created by these events also.The same files will be copied again during the
> first incremental replication just after the bootstrap. In normal scenario,
> the duplicate copy does not cause any issue as hive allows the use of target
> database only after the first incremental. But in case of migration, the file
> at source and target are copied to different location (based on the write id
> at target) and thus this may lead to duplicate data at target. This can be
> avoided by having at check at load time for duplicate file. This check can be
> done only for the first incremental and the search can be done in the
> bootstrap directory (with write id 1). if the file is already present then
> just ignore the copy.
