Description

This is a random issue happens in Impala 3.4.0 env:

1. has sentry installed
2. high concurrency on impalad
3. happens on view that calls buildin functions

It looks that restart impalad solves this problem. We should add more info in exception string to help identify the issue when it happens again.

Error message as below:
