-----------------------------------
I will fix it on Pig side (PIG-4373). Please close this ticket.
> Hadoop 3 Pig (with Tez) action shall not use given distributed cache

> Key: OOZIE-3300
> URL: https://issues.apache.org/jira/browse/OOZIE-3300
> Project: Oozie
> Issue Type: Bug
> Components: action
> Affects Versions: 4.3.1
> Environment: Oozie-4.3.1
> Hadoop-3
> Reporter: Denes Bodo

> When I run my Pig action and set -x Tez to use Tez as the execution engine, I
> got the following error:
> {code:java}
> Caused by: java.lang.RuntimeException:
> org.apache.hadoop.mapred.InvalidJobConfException: cache file
> (mapreduce.job.cache.files) scheme: "hdfs" host: "mycluster" port: -1 file:
> "/tmp/temp257132233/hive-exec-3.0.0.3.0.0.0-1469.jar" conflicts with cache
> file (mapreduce.job.cache.files)
>
> hdfs://mycluster/user/oozie/share/lib/lib_20180611041054/pig/hive-exec-3.0.0.3.0.0.0-1469.jar
> {code}
> or
> {code:java}
> Caused by: java.lang.RuntimeException:
> org.apache.hadoop.mapred.InvalidJobConfException: cache file
> (mapreduce.job.cache.files) scheme: "hdfs" host: "ns1" port: -1 file:
> "/tmp/temp36150863/joda-time-2.9.6.jar" conflicts with cache file
> (mapreduce.job.cache.files)
> hdfs://ns1/user/oozie/share/lib/lib_20180612003013/pig/joda-time-2.9.6.jar
> {code}
> When I exclude the conflicting jar, then Pig cannot start due to class not
> found exception.
> I think a workaround or solution? could be if we exclude the
> *mapreduce.job.cache.files* and *mapreduce.job.cache.archives* from
> pig.properties file.
>
> It is a bit scary change because I am not sure if the user's job shall use
> specific driver or implementation which needs to be on distributed cache.
