Review Comment:
was thinking about this: please be aware that this catch here is just a best
effort - and so it's the catch and re-throw antipattern, couldn't help with
that - so I decided to not raise it above LOG.error, as the exception is 99.9%
is going to be logged again, as HS2 cannot help with tez session opening
problems, so this is "just an FYI", does it make sense?
