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

Best Regards,
Karim Ahmed Awara
