Subject disable checksum
Date Mon, 24 Jan 2011 21:15:00 GMT
Hello,

Is it possible to disable checksum in the Hadoop framework when I run my 
MapReduce program? so no checksum is generated for outputting data, it 
isn't verified by the last node in the pipeline and isn't verified when 
a client reads it.
I know DistributedFileSystem.setVerifyChecksum() can disable the client 
to verify checksum, but how to avoid checksum being generated and 
verified by the datanode?

Best,
Da
