I’ve read from several thread in this community about sending file over spark 2.8.3. But many of them doesn’t successfully to do this. However, is there any prerequisite to do this with p2p networking? How I can configure to enable this feature?
File transfer is broken in 2.8 versions. There is a fix for 2.9.0 version, but it is not know when it can be released. If you really need file transfer, you can use 2.7.7 or try 2.9.0 nightly build and enable IBB transfers.
