Comment (by neverline@…):

 updated ''nicholas'' Portfile to work on latest 10.10 with latest Java 8
 from oracle, there are still some issues that you have to uncomment config
 variables with paths, and for some reason it doesn't start by launchd, but
 starts fine with sudo passing the same params. Also cqlsh doesn't work otb
 and requires additional ''pip install cassandra-driver''.

 Would be great if somebody could take care of this port! Thanks
