guys, i have some problems on seq_id

1. what is the motivation of adding seq_id as part of the bulkload files

2. why introduce the conf hbase.mapreduce.bulkload.assign.sequenceNumbers in class loadIncrementalHFiles,
if this is true, every time we flush, should first do a flush

3. now if we compact two files, seq_id are 3 and 7, the file after compact will get seq_id
from region, may be 12
if i make the file after compacted seq_id=7, the largerest seq_id among compacted files,
will cause any serious problems?

the version is hbase0.98.10

thanks
