             Summary: 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
            Assignee: 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}
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}
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.
