In case of errors in user computations the Ignite Compute Grid produces a
lot of errors into the log.
In the worst way it produces the next messages:
1. Failed to execute job: …
2. Failed to reduce job results: …
3. Failed to execute task: …There is a suggestion to decrease log level for first and second messages to DEBUG level, because of the third message will still be shown. -- Vasiliy Sisko
