Subject Write operation in TestDFSIO
Date Tue, 07 Feb 2012 10:06:25 GMT
Hey guys,
       I performed TestDFSIO benchmark on my hadoop cluster (1namenode and
2 datanodes).
       The benchmark was run for different number of files constituting
200mb size.
       The following image is a graph of the throughput IO rate against
number of files.
       I want to know why the write operation is varying this way. There is
no pattern of constant increase or decrease.[image: WriteOperation.png]
