> While trying to use a custom classpath for metastore jars (spark.sql.hive.metastore.jars pointing at some filesystem path), I ran into the following issue:
> {noformat}
> java.lang.ClassNotFoundException: java.lang.NoClassDefFoundError: org/apache/hadoop/mapred/MRVersion when creating Hive client using classpath
> {noformat}
> The issue here is that {{MRVersion}} is not packaged anywhere with Spark, and the code in {{IsolatedClientLoader}} only ever tries the parent class loader when loading hadoop classes in this configuration. So even though I had the class in the list of files in {{spark.sql.hive.metastore.jars}}, Spark never tries to load it.
