             Summary: ClassNotFoundException for class dependency in external jar while running Gobblin with mapreduce mode
                 Key: GOBBLIN-1671
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-1671
             Project: Apache Gobblin
          Issue Type: Bug
    Affects Versions: 0.16.0
            Reporter: Bharath Krishna


Faced issue while trying to upgrade from Gobblin {{0.14}} to {{0.16.}}
We have a 'Gobblin consumer' jar, which contains some consumer/job implementations.
We pass the consumer jar along with some other jars through the {{--jars}}  field in gobblin.sh MapReduce mode ([https://github.com/apache/gobblin/blob/b400089035fe7ada1a523f9b7e5321e11d46d651/bin/gobblin.sh#L129])

 

It is noticed that the Gobblin runs fail with ClassNotFoundException, not able to find the classes from the consumer jar, although it is present in the {{libjars}} as well as the {{HADOOP_CLASSPATH}}

{{}}
One workaround for this is to copy the custom jar onto [GOBBLIN_LIB|https://github.com/apache/gobblin/blob/b400089035fe7ada1a523f9b7e5321e11d46d651/bin/gobblin.sh#L30], although this does not seem correct as the consumer jar should have been already included through  {{--jars.}}
