------------------------------------
Feedback from Joel Baranick in Gobblin lobby:
If I recall, fork and typesafe config have issues.
We had to write the config for our job with Forks like:
_converter.classes.ROOT_VALUE="..."
...
converter.classes.0="..."
...
converter.classes.1="..."_
Above change in config got rid of the issue.
Subsequent comment from Joel: Created: apache/incubator-gobblin#2164
> Exception when using fork followed by converters with EmbeddedGoblin

> Project: Apache Gobblin
> Issue Type: Bug
> Components: misc
> Reporter: atif majid
>
> Have a simple Gobblin job that is run using
> gobblin.runtime.embedded.EmbeddedGoblin class. There is a fork in the job
> followed by converters for each fork. Using converters in fork branches
> results in below exception - note that there is a converter before the fork
> and then converters for each branch of fork that have been specified using
> converter.classes.<fork_number>. If no converters are used in fork branches
> then this exception is not encountered.
> com.typesafe.config.ConfigException$BugOrBroken: In the map, path
> 'converter.classes' occurs as both the parent object of a value and as a
> value. Because Map has no defined ordering, this is a broken situation.
