> There is a jackson.datatype.guava library conflict problem in HiveToDruidTransfer when hive and druid has different library version.
> In my case
> hdp version: 2.6.3.0
> druid version : druid-0.10.1( jackson-datatype-guava-2.4.6.jar)
> We should be able to set this property to solve that problem.
> "mapreduce.job.user.classpath.first" : "true"
> It means "prefer loading Druid's version of a library when there is a conflict".
> reference. [http://druid.io/docs/latest/operations/other-hadoop.html] (Tip #2)
> But Job properties is hard coded in HiveToDruidTransfer.

> This is the error message I got.
