thank you for your help, Sourav.
i found broadcast_0 binary file in /tmp directory. it's size is 33.4kB, not
equal to estimated size 135.6 KB.
i opened it and found it's content has no relations with my read in file. i
guess broadcast_0 is a config
file about spark, is that right?

Apart from user defined broadcast variable, there are others which is being
created by spark. This could be one of those.
As I had mentioned you can do a small program where you create a broadcast
variable. Check the broadcast variable id(say its x). Then go to the /tmp
to open broadcast_x
