Wrong version advertised by library terminology client

[johngrimes]

It seems like the wrong git.properties file is being picked up from this distribution of the software, probably due to there being multiple within the JAR.

To reproduce this, use the no-argument PathlingContext.create() within the Python library, and take a look at the User-Agent header attached to terminology requests.

This is again a problem with classpath precedence within the Spark environment.

There are other dependencies within Spark that have git.properties files within them. Setting spark.executor.userClassPathFirst to true fixes the problem.

We might just have add this configuration to the default creation within PathlingContext.create, and also update the guidance for installing in your own cluster / Databricks.

This is again a problem due to some subsequent changes in the way that the Spark classpath gets put together in some contexts.

We need a more robust solution to this problem.

Fixed in #1189.
