Bisakah Spark dikonfigurasi sehingga alih-alih mengikat ke alamat 127.0.1.1 untuk port 7077, malah bisa terikat ke 0.0.0.0 . Dengan cara yang sama seperti port 8080 terikat:
netstat -pln
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

Alasan saya menanyakan hal ini adalah karena saya tidak dapat menghubungkan pekerja ke node utama dan menurut saya masalahnya adalah ip master tidak dapat ditemukan.
Kesalahan saat mencoba menghubungkan budak ke master:
