Hi all,
We tried using mapreduce to execute a simple map code which read a txt
file stored in HDFS and write then the output.
The file to read is a very small one. It was not split and written
entirely and only in a single datanode (node A). This node is
configured also as a tasktracker node
While we was expecting that the location of the map execution is node
A (since the input is stored there), from log files, we see that the
map was executed in another tasktracker (node B) of the cluster.
Am I missing something?
Thanks for the help!
