我正在开发 Zeppelin 0.7.1，我需要使用弹性搜索火花依赖项和 play-json 依赖项。然而，这两者由于某种原因彼此不兼容。如果我删除 json 依赖项，es-spark 工作正常。我添加它的那一刻，解释器就中断了。

以下是口译员：

org.elasticsearch:elasticsearch-spark-20_2.11:5.4.1

com.typesafe.play:play-json_2.11:2.6.0-M5
(exclude) com.fasterxml.jackson.core:jackson-databind

以下是错误信息：

排除的杰克逊数据绑定不是问题。尝试了有和没有它，但没有任何改变。
