Date Sat, 06 Sep 2008 04:11:00 GMT
hello. I'm a new user to hadoop. and Now I hava a problem in understanding
Hdfs.
In such a scene.  I have several databases and  want to index them.  So when
I map indexing database, I have to control which database index was stored
in which datanode. So when database updated, The index can be updated
correspondely.
So how can i get to do this? thanks
