Subject HBase RegionServer and Hadoop : Basic Question
Date Mon, 27 Oct 2008 13:33:56 GMT
Hi All

I've looked at http://wiki.apache.org/hadoop/Hbase/HbaseArchitecture but I
couldn't get a sure answer. This is a basic question , but it will clearify
a lot of things for , so your answer is appreciated :)

When I'm entering 256Mb of data to a table , the data itself is stored on
Hadoop DFS  (256Mb) and the RegionServer *MapFile* (in the memcahe) contains
the reference to the location of the row "war and peace" ?

A RegionSplit occurs when the MapFile is bigger then 256Mb (default) or when
the *content* stored on Hadoop DFS specific location is greater the 256Mb?

Thanks!
