使用版本：
zeppelin：0.7-SNAPSHOT
spark：1.6.2-hadoop-2.6-cloudera
详情：
com.fasterxml.jackson.databind.JsonMappingException: Could not find creator property with name 'id' (in class org.apache.spark.rdd.RDDOperationScope)
at [Source: {"id":"0","name":"textFile"}; line: 1, column: 1]
更改 zeppelin 的 jackson 为2.4.4 ，spark1.6.2为2.4.4保持一致
