Description

Right now we do not know what happened during startup failure,
because there no records in the logs.
I propose to change main() so that it would catch exceptions and
log them rather then throwing them into std out.
May be the same should be done for the JobTracker.
The TaskTracker.main() catches at least the IOException.
