Jun Zhang commented on FLINK-16539:
-----------------------------------
If the attribute value is an int type with spaces in front, the system does not
remove the spaces. When using Integer.valueOf () function to verify it, an
error will be thrown, we just remove the spaces before and after
> sql client set param error
