Spark takes lot of time to initialize when the network is not connected to internet.

Hi, I have faced two problems in using Spark ML when my network is not connected to the internet (airplane mode). All these issues occurred in windows 10 and java 8 environment.

1. Spark by default searches for the internal IP for various operations. (like hosting spark web ui). There was some problem initializing spark and I have fixed this issue by setting "spark.driver.host" to "localhost".
2. It takes around 120 secs to initialize the spark. May I know that is there any way to reduce this time. Like, If there is any param/config which related to timeout can resolve this?
