Subject trace class calls in hadoop hdfs
Date Mon, 04 Nov 2013 09:24:44 GMT
Hi,

I want to trace the calls that both the DataNode and the NameNode do when I
execute a shell command on the hdfs such as (hadoop dfs -put {src} {dst}).
Any idea how to do that?


; tracing including the data node asking the name node for the blockID..
also the class where datanode use to determine the replica datanodes in the
pipe ..etc
