Nikolay,
First the error is printed on the map node, then on the reduce node, and
then the exception is thrown from the method that triggered the execution.
The compute grid seems to use the "print an error message and delegate
exception to the caller" which doesn't make much sense.
If you don't know what to do with an error and delegate it to the caller,
what's the point in printing it to log?
This is the kind of information that should only be printed when debug
logging is enabled.
I created a ticket for this issue:
https://issues.apache.org/jira/browse/IGNITE-13487
