remove_alias.sh lead to errors using InetAddress.getLocalHost.getHostAddress

[clakech]

Hi,

Thanks for sharing your work, I am now running a spark cluster in minutes on my laptop, cool!

But when I submit some code to the cluster, it fails because of the remove_alias workaround.

When I try to use InetAddress.getLocalHost.getHostAddress I face an exception:

java.net.UnknownHostException: 34a5ed171df7: Name or service not known

The code I am using is the spark-cassandra-connector. The exception is thrown here: https://github.com/datastax/spark-cassandra-connector/blob/v1.3.0-RC1/spark-cassandra-connector/src/main/scala/com/datastax/spark/connector/cql/CassandraConnectorConf.scala#L108

If I remove the remove_alias from the spark-shell launcher, the spark-cassandra-connector works but later when spark "deploy" the submitted code to its cluster of worker, there is an error because the nodes try to use their internal names to communicate.

Seems like a linking problem. I will trying to remove the remove_alias workaround and to link each node properly for them to communicate using their names

I may a found a solution to this by solving the remove_alias workaround properly #2
