Re: M/R Staticstics


I was able to overcome the permission exception in the log by creating
an HDFS tmp folder (hadoop fs -mkdir /tmp) and opening it up to the
world (hadoop fs -chmod a+rwx /tmp). That got rid of the exception put I
still am able to connect to port 50030 to see M/R status. More ideas?

Even though the exception was missing from the logs of one server in the
cluster, l looked on another server and found essentially the same
permission problem:

   do you see "retired jobs" on job tracker page. There is also "job
tracker history" on the bottom of page. 

something like this  http://nn.zettabyte.com:50030/jobtracker.jsp

When I submit a simple "Hello World" M/R job like WordCount it takes
less than 5 seconds. The texts show numerous methods for monitoring M/R
jobs as they are happening but I have yet to see any that show
statistics about a job after it has completed. Obviously simple jobs
that take a short amount of time don't allow time to fire up any web
mage or monitoring tool to see how it progresses through the JobTracker
and TaskTracker as well as which node it is processed on. Any
suggestions on how could see this kind of data *after* a job has
completed?
