Hi, In TestLoadIncrementalHFiles's runTest method, a hfile is created for each hfile region (between lines 133-138). http://svn.apache.org/viewvc/hbase/trunk/hbase-server/src/test/java/org/apache/hadoop/hbase/mapreduce/TestLoadIncrementalHFiles.java?view=markup
I couldn't understand the reason for such an action.. It is obvious that SPLIT_KEYS is used for splitting table into regions, but what is the use of hfile regions? Even I wrote all keys into one file, bulk load works... Does writing into different files according to ranges increases the performance? And how should I decide range boundary values? thanks in advance..
