I read some documents and still confused. can any one please clarify me : what is HLog,storefile.Hfile and store? I am looking for a simple flow to understand what is written to these files. looking for a simple PUT and GET I was aware of the WAL file in general. your clarifications will be really appreciated and also sorry for asking the basic question -Adi ---1508073814-52025219-1321338309=:29031--
