val a = new Something() .someMethod() .someMethod2() in 0.7.3 but it doesn't in 0.8.0 ... it says the .someMethod(), etc. are an illegal start of expression.
Some of these setups I have are fluently expressed but would be unmanageable in a single long line. Is there something I need to do to re-enable this so that my existing pool of zeppelin notebooks still all work as they did before?
This behavior is coming from the new spark interpreter. Jeff opened ZEPPELIN-3587 to fix it. In the mean time you can use the old spark interpreter (set zeppelin.spark.useNew to false) to get around this. Hopefully you aren't dependent on the new spark interpreter.
