Re: RCFile vs SequenceFile vs text files
The thing about OCR is that it is great for tables created from other
tables, (like the other columnar formats) but if you are logging directly
to HDFS, a columnar format is not easy (possible) to write directly.
Normally people store data in a very direct row oriented form and then
there first map reduce job buckets/partitions/columnar-izes it.
