Answer 1

The problem is with the filename you are using "~/ayush/output/part-00000" relies on Unix shell (sh, bash, ksh) tilde expansion to replace the "~" with the pathname of your home directory.

Java (and C, and C++, and most other programming languages) don't do tilde expansion. You need to provide the pathname as "/home/ayush/output/part-00000" ... or whatever absolute pathname it is that the tilded form expands to.

Strictly speaking, the URI should be created as follows:

new File("/home/ayush/output/part-00000").toURI()

not as

new URI("/home/ayush/output/part-00000")

The latter creates a URI without a "protocol", and that could be problematic.
