Review comment:
Yeah I agree that the worst case is that commit hash won't be returned,
but what I'm interested in here is to show any informative message for **pinot
dev/ admin** to help debug the exception instead of silently swallowing it.
We've already had the try catch blocks here, it'd be good to make use of it.
I'm fine with keeping it as is, just a good to have.
