Exclude jackson-databind from shaded jar #50

Open jrkinley opened 3 years ago

jrkinley commented 3 years ago

Exclude jackson-databind from shaded .jar as it clashes with Spark's version in Cloudera Runtime 7.1.x. Looking at the dependency tree Spark includes jackson-databind:2.6.5 whereas Envelope 0.7.2 is including jackson-databind:2.3.1 as part of a kitesdk dependency.

Spark throws this exception when both versions of the jar are on the classpath:
