commit a5099a2d3b3bdfd4bb21361ffc1ed61b4195bbe8
Author: Mingyu Chen <morning...@163.com>

    [minor](log) print error msg to fe.out before log is initialized (#22106)
    
    The exception may be thrown before LOG is initialized.
    Such as wrong config value. So we need to print it to fe.out, otherwise
    we can't know what's wrong.
    
    After this PR, the error can be found in fe.out, such as:
    
    ```
