The master branch don't have this problem. So should create another pr on
branch 1.6?[~hvanhovell]

I have checked, backticked identifiers don't have this problem. However, I
still think it should be fixed.

Could you check if backticked identifiers have this problem? That might be
another way out of this.

A table identifier starting with a number will work here but the one starting
in the form of scientific notation like “1e34” will cause this problem. In
fact, when SqlParser.parseTableIdentifier parses an identifier like "1e34abcd",
the first token it will come across is "1e34" and it will see it as a number,
not an valid identifier.

What does scientific notation have to do with it? it's a table identifier. Is
it the fact that it starts with a number?

We overhauled much of the parser infrastructure (including parsing
TableIdentifiers). Could you try this on master first?
