| Comma-separated paths of the jars that used to instantiate the HiveMetastoreClient.
| This configuration is useful only when `{$HIVE_METASTORE_JARS.key}` is set as `path`.
| The paths can be any of the following format:
| 1. file://path/to/jar/foo.jar
| 2. hdfs://nameservice/path/to/jar/foo.jar
| 3. /path/to/jar/ (path without URI scheme follow conf `fs.defaultFS`'s URI schema)
| 4. [http/https/ftp]://path/to/jar/foo.jar
| Note that 1, 2, and 3 support wildcard. For example:
| 1. file://path/to/jar/*,file://path2/to/jar/*/*.jar
| 2. hdfs://nameservice/path/to/jar/*,hdfs://nameservice2/path/to/jar/*/*.jar
