According to sbt/sbt#3240 , this error is due to jline and new curses library.

The error in sbt seems to be fixed on sbt 1.0.2 but sbt 1.x requires Scala 2.12 which does not build latest (2.3.1) Spark. (Spark 2.x is built on Scala 2.11)

You may work around by setting TERM variable as xterm-color instead of xterm-256color.

export TERM=xterm-color
