@cloud-fan Yeah wenchen. so first time we invoke analyzer is on this line.
And upon exception we go to catch block -
```
case e: AnalysisException =>
val ae = new AnalysisException(e.message, e.line, e.startPosition,
Some(analyzed))
```
and call analyzer the second time while trying to evaluate the last
parameter - Some(analyzed) ?
