Bharath Krishna updated GOBBLIN-1671:
-------------------------------------
Description:
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.}}
