Describe the bug

@intr3p1d
In docs ver 3.0.0, still let developers to use this pinot sciprts which is just latest one (master branch).
But, as you know, the table name "ExceptionTrace" is not applied for ver 3.0.0
So, I think it will be better to write fix comments like you described in here

What did you do to trigger the bug?

Just run Pinpoint Web and got exception log from web.

Expected behavior

Like above, just put more comments about it or fix the link to excpetionTrace scripts.

Logs

If applicable, please attach agent/collector/web DEBUG log that includes the code execution that led to the bug. In case of agents, including the start-up log may be of great help.
