Subject The problem about block size
Date Wed, 10 Aug 2011 08:33:18 GMT
Hi,
I have established a Hadoop cluster with one NameNode and two DataNodes.
Now I have a question about block size. I site the block size for 64MB.I stor one text file
(50MB) on the HDFS. Whether this text file  is splited? If not, the text file stor on which
DataNodes? I user MapReduce to comput the text file, how many maps will process this file?
Please forgive my poor English.
Best regards! 
Cheng Xiao
