Hi,
I am using mapreduce to run the job but when I try to run the job in
mapreduce by clicking run button I am getting error like this :
Error -- java.lang.RuntimeException: Full stack trace is available in
the server logs. Message: Got an IOException while trying to make
splits
In my local machine mapreduce works fine, It executed the job without
any error.
I am using app engine sdk 1.3.8
Following is the server log generated by my application for the
mapreduce error.
