I had an online question on this commit.. posting it here in case it was missed.
https://github.com/apache/zeppelin/commit/f28e9631737da554a0a12323f6c00ccae3ec6282#r35696882 I noticed that when I built zeppelin from source that my spark interpreter no longer worked. I think it is this commons-lang3.version that is causing it. "java.io.InvalidClassException: org.apache.commons.lang3.time.FastDateParser; local class incompatible: stream classdesc serialVersionUID = 3, local class serialVersionUID = 2 " Spark is delivered with commons-lang3-3.5.jar but replacing it with commons-lang3-3.7.jar fixed the issue. Rather than modifying spark, should we deliver a compatible jar in the interpreter/spark directory?
