    Attachment: hbase-3474.txt

Hi Ashish. I took your patch and cleaned up the unit tests a bit to share some of the mocking code. I also added a {{getCompressionAlgorithm}} call to {{HFile.Reader}} as you suggested.

I removed one of the unit tests since it seemed to be entirely subsumed by the other one. Also updated the unit tests to check cases like 0-CF and 1-CF.

Can you check over this updated patch and make sure it looks good to you?

> HFileOutputFormat  currently creates HFile writer's using a compression algorithm set as configuration "hbase.hregion.max.filesize" with default as no compression. The code does not take into account the compression algorithm configured for the table's column family.  As a result bulk uploaded tables are not compressed until a major compaction is run on them. This could be fixed by using the column family descriptors while creating HFile writers.
