AVRO-2644: Fix deterministic directory compilation
> Non-Deterministic avsc Directory Compilation
> --------------------------------------------
>
> Key: AVRO-2644
> URL: https://issues.apache.org/jira/browse/AVRO-2644
> Project: Apache Avro
> Issue Type: Bug
> Reporter: Austin Cawley-Edwards
> Priority: Minor
>
> {color:#222222}We're trying to use the `compile \{src dir} \{output dir}`
> command in{color}
> {color:#222222}`avro-tools` and finding that there are some
> non-deterministic{color}
> {color:#222222}behaviors between systems, depending on how the OS sorts
> files.{color}
> {color:#222222}Example:{color}
> {color:#222222}schemas/Component.avsc{color}
> {color:#222222} - defines Component record type in the namespace
> `com.test`{color}
> {color:#222222}schemas/Parent.avsc{color}
> {color:#222222} - defines a Parent record, in the same `com.test`
> namespace, with a{color}
> {color:#222222}field of type `com.test.Component`{color}
> {color:#222222}With the command, `java -jar avro-tools-1.9.1.jar compile
> schemas/{color}
> {color:#222222}out-dir/`, some systems compile the directory in the order
> Component,{color}
> {color:#222222}Parent while others compile in the order Parent, Component.
> The latter{color}
> {color:#222222}fails as Component has not been defined when it is referenced
> by{color}
> {color:#222222}Parent.{color}
> {color:#222222}We have also tried using the IDL and importing the dependency
> types,{color}
> {color:#222222}and then converting them to avsc, and finally compiling the
> entire{color}
> {color:#222222}directory, but that fails as the generated avsc files embed/
> duplicate{color}
> {color:#222222}the "Component" types each time it is used.{color}
> {color:#222222}OS:{color}
> {color:#222222}Linux 857aaf92e059 4.15.0-70-generic #79-Ubuntu SMP Tue Nov

> Would a PR be accepted that enforces LANG=C semantics or would that have to
