-/**
- * NOTE: This class is a copy of the SchemaRegistryClient from https://github.com/hortonworks/registry.
- * The changes to this file are the following:
- * - Making the 'private Login login' become protected for access by sub-classes
- * - Making the 'private Configuration configuration' become protected for access by sub-classes
- *
- * This is the default implementation of {@link ISchemaRegistryClient} which connects to the given {@code rootCatalogURL}.
- *
- * An instance of SchemaRegistryClient can be instantiated by passing configuration properties like below.
- *
- * SchemaRegistryClient schemaRegistryClient = new SchemaRegistryClient(config);
- *
- *
- * There are different options available as mentioned in {@link Configuration} like
- *
- * - {@link Configuration#SCHEMA_REGISTRY_URL}.
- * - {@link Configuration#SCHEMA_METADATA_CACHE_SIZE}.
- * - {@link Configuration#SCHEMA_METADATA_CACHE_EXPIRY_INTERVAL_SECS}.
- * - {@link Configuration#SCHEMA_VERSION_CACHE_SIZE}.
- * - {@link Configuration#SCHEMA_VERSION_CACHE_EXPIRY_INTERVAL_SECS}.
- * - {@link Configuration#SCHEMA_TEXT_CACHE_SIZE}.
- * - {@link Configuration#SCHEMA_TEXT_CACHE_EXPIRY_INTERVAL_SECS}.
- *
- * and many other properties like {@link ClientProperties}
- *
- *
- * This can be used to
- * - register schema metadata
- * - add new versions of a schema
- * - fetch different versions of schema
- * - fetch latest version of a schema
- * - check whether the given schema text is compatible with a latest version of the schema
- * - register serializer/deserializer for a schema
- * - fetch serializer/deserializer for a schema
- *
