之前用的版本是zeppelin0.7.2和spark1.6，最近把zeppelin升级到0.8发现1.6的配置和2.2的配置默认都无法支持，大概会遇到3个问题。

1. Incompatible Jackson version: 2.8.11-1
   jackson版本问题
   rm zeppelin/lib/jackson-*
   cp $spark_home/jars/jackson-* zeppelin/lib/
   就可以解决了

2. org.apache.spark.network.client.TransportResponseHandler.channelInactive
   这个是因为netty包版本不一致问题导致
   同样
   rm zeppelin/lib/netty*
   cp $spark_home/jars/netty* zeppelin/lib
   搞定了

3. spark版本未识别
   在zeppelin interpreter 中，配置SPARK_MAJOR_VERSION 值为2
   其他参数如果需要可以参照，按照个人喜好来吧
