Jun Zhang commented on FLINK-16539:
-----------------------------------
I found that the system did a trim operation when parsing the command line, but
did not do a trim operation on the value. Besides, I don’t know if the trim
will affect other commands except the set command,so I add the trim to the
callSet method. [~ykt836]
